sounds good to me... thanks

GTATransAM

That looks like a pretty damn good deal. I was looking to spend over $1100 for a complete exhaust setup, headers, catback, converter, cutout. With that deal id be looking at about $860, hmm......

And there all coated huh, thats pretty good, id gotta think about this deal, it sounds good. Only 2 things im worried, is the 1 5/8 sizing, i thought 1 3/4 was the "ideal" size for 350s. And also the resonaters on the catback, wont it make it to quiet?

DuffMan

iTrader: (1)

GTATransAm,

I think 1 5/8" is enough, even for built 350s. Also, there are not any resonators on the cat-back. It simply bolts onto your stock cat and is piping all the way to the Flowpath muffler to the regular or chrome tailpipes.

Thanks,
Eric

3" Off-Road "Test Pipe" w/ A.I.R. : $59.97

Is this piece meant to be a pipe that will fit in place of the cat? Meaning bypassing the cat?

DuffMan

iTrader: (1)

yes, it replaces the cat completely and makes it free flowing (and also illegal for california cars i'm sure)

However, the AIR provision is there so your car won't throw any codes. The guy at MAC told me its good for 5-7 horses ("bypassing" the cat that is)

eric

semiller26

By illegal do you mean that they won't sell it to me?

DuffMan

iTrader: (1)

no no, not at all. just that if you do get pulled over and the cop is dick enough to check under your car, no cat is illegal, but Performance Audio will still sell you the cat-delete

in fact, when i had my RS, the guy suggested to me that I be able to do a quick switch between the cat and the "test-pipe" for when I go racing

eric

mw66nova

iTrader: (13)

what cat do you suggest using with this system? i mean if you went with their headers, y-pipe, and catback, who makes a cat that bolts right up? how much and where to get it?

DuffMan

iTrader: (1)

Hey,

Well, their system bolts up to the stock cat, so whatever cat you look at, as long as it states it will bolt to stock exhaust, then it will (logically) fit the MAC system. You can use MAC's cat, and it flows VERY well as it is a Hi-Flow design, but you can use any cat you wish (again, as long as it fits). The only other cat I would personally use would be Random Technology cat, but those are more expensive than MAC, so I would just go with a full MAC exhaust, but again, its up to you

Thanks,
Eric

mw66nova

iTrader: (13)

how much hp do you think this sytem will support. i have heard people running low 12's high 11's on the flowmaster single in/single out system. that is what i am looking at right now. i am considering MAC headers and a flowmaster catback with a cheap high flow cat.

DuffMan

iTrader: (1)

11-12 range will work with MAC. Here is an interesting fact that most poeple don't know : MAC mufflers (FlowPath) outflow Flowmaster! I don't have the specific flow rates on me, but if you are interested in that info, e-mail me at duffmanrha@hotmail.com and i can send over that info.

You can get a cat for like 60-70 at any auto parts store, but they are not hi-flow (but they get the job done very well). MAC hi flow cat's are usually in the 100-130 range, but that is comparable to other company's cats.

My personal recommendation to you would be to just get all MAC stuff - not because I am runnig this GP, but because I really do think they are the best for the money (not to mention MAC sounds great and not raspy at high RPMS like flowmater)

Lemme know if you want that Flowmaster vs. MAC flow tests info, but again, it is all up to you. you won't hurt my feelings if you onlt get the headers/y-pipe

Eric

mw66nova

iTrader: (13)

alright man, here's the deal. i have a 1989RS sitting in my parents driveway that i just totalled. i have all kinds of court fees and stuff coming up that i have to pay off first. i have a very wild 305 right now that should put the car in the mid/low 13's. i am also building another 350 in the not-so-near-but-not-really-far future. lol. so, as you can see, i am being hit up for some serious cash right now. i got a guy i DE looking for a camaro for me that he said he would send to me for free (yeah, free car!) but i still need exhaust as my "custom" true dual exhaust was destroyed in the wreck. hedman lt's and moroso spirals. i don't think i will be able to get the money for the exhaust before the end of the deadline cause of bills/rent/court fees/fines. i need to know if these products are worth paying full price. if i bought the headers/cat/catback, would it be comparable to the power i had with my dual system? see my predicament(sp?)?

edit: i do want a "stock style" exhaust for ground clearance purposes.

DuffMan

iTrader: (1)

Well to answer your question, I would defintely pay full price for this, because in my opinion it is just as good, if not better than products similiarly priced.

However, I do understand your situation, so please e-mail me and we may be able to work something out regarding your situation!

Thanks,
Eric

87350IROC

iTrader: (2)

what kind of coating is HTS, is it comparable to Jet Hot?

DuffMan

iTrader: (1)

87350IROC,

no it is not comparable in quality to jet hot (of course, neither are any other coatings from other headers unless it specifically says ceramic coating, which applies to T.E.S. headers, etc.)

of course, you could always have the MAC headers shipped to ACS (and STILL end up with a superior product for less)

I want to run two test-pipes instead of my dual cats... but I want to make it look like I still have the cats by putting the cat shells around the test pipes. Will the MAC 3" test pipe fit into the shells? Or would I need to get a smaller test pipe, like 2.5" or 2.75"?

DuffMan

iTrader: (1)

the MAC pipe is designed to replace the cat, i don't think it will fit inside the cat shell. I know what you are describing, I just don't think it will be feasible, unless you want to replace teh test pipes with teh cats every 2 years to smog.

eric

DuffMan

iTrader: (1)

Ok, we have had one person place an order for a full exhaust, thanks Robert! This offer is not going to last forever, so if anyone is interested, they are encouraged to contact me for any questions, or if you would like to place an order, follow the instructions above!

Thanks,
Eric

Pepsicola

Is there a deadline to the GP yet?? I don't have any money yet I need to work OT but they are not offrering it

DuffMan

iTrader: (1)

pepsicola,

no announced deadline as of yet, but i'm not sure when that will be, just want to try to drum up support no worries on the money issue, i completely understand not having any cash there is talk of setting up a site with these prices in the near future, and if it is, i may be put in charge of handling it and I will defintely post the info here again whenver that day comes. however, that is not set in stone, so everyone is still encouraged to take advantage of this if possible

89_305TransAm

Is this GP still going on? and if so for how long?

DuffMan

iTrader: (1)

see above post

89_305TransAm

Is this a GP that everyones orders are processed once its over or are the orders proccessed and shiped as they come in?

DuffMan

iTrader: (1)

they are processed on an individual basis. one person ordered the entire exhaust (headers, y-pipe, test pipe, cat-back) and the headers,y-pipe and cat-back went out same day and the test pipe is going out end of the week (back ordered on that part). depending on the size of the order, and the status of the parts, it could be same day, or a few days, but its not like you'll be waiting MONTHS for your stuff

eric

EDIT : forgot to mention that whenever your order is processed after you place it, you will receive a tracking number (they use UPS) for your package, so you'll know the status

DuffMan

iTrader: (1)

89_305TransAm

Sounds awesome. Im defintily gonna get myself in on this GP before its over. Test pipe here i come

GTATransAM

Hey Duff i just emailed those guys to order the Cat-Back and Header System. So now im waiting for that phone call Plus i got a Hi-Flow converter and Cut-out, plus Sub-Frame connectors too from somewhere else.

Heres the link:

https://www.thirdgen.org/techbb2/sho...hreadid=222438

Ah this Summer is gonna be a blast

GTATransAM

Update: Just got the phone call......very fast. So its all set now

DuffMan

iTrader: (1)

GTATransAm - glad to hear that you got some exhaust! they are usually really good about shipping that stuff out, so if you placed it today it will prolly go out monday (weekend and all) unless it is backordered, which does happen (but it WILL go out)... somtimes they go out same day

they also told me to remind everyone that MAC suspension can also be ordered, but if you are intereted in that, e-mail me and i will talk to them directly!

89_305TransAm - the MAC full exhaust (headers, y-pipe, hiflo-cat, cat-back) really woke up my 305, so i would defintely give it 2 thumbs up. (of course, if you don't live in california, you can get a test pipe for more power AND less money than a cat)


good job so far guys!

Cool! Thanks, Duffman. I just found your topic here--and just in time! I was just about to place an order with Mac. Since I'm so close to them, I'd emailed to make sure I could pick it up instead of having it shipped. So this is great!

DuffMan

iTrader: (1)

I'm sure if you wanted to save on shipping you can probably pick up the exhaust stuff in Colton. Call Rick and ask about that if you are interested, but you will have to pay for sales tax anyway, whether you had bought it from MAC or through the GP (so i guess saving on shipping is a wash)

glad that you found the GP helpful, and if you could, feel free to spread the word to as many people as you can! this goes for anyone of course

eric

LAFireboyd

iTrader: (3)

Hey, Eric, I've written Mac about this, but it might take a couple of days to get a response, so I thought I'd try here, too.

This is probably a silly question, but I've never messed with the manifolds or headers. So regarding that Y-pipe only, they say it's a stock replacement. But it's 2 1/2" tubing, and aren't our stock manifolds 2 1/4"? If the pipe really FITS stock, then does it narrow to 2 1/4" for the connection; or do they use an adapter of some kind for the smaller connection; or is it only "stock" in shape, and it really only works with their, or other's, headers that are also 2 1/2"?

I love the price of the pipe/header combination, and the headers have the air tubes and O2 fitment(it said, I believe) for a legal set-up, so the thought of the entire system is definitely exciting, but it's more than I really wanna mess with.

So if you, or anyone else, is familiar with these Mac products, I'd love to know if this'll fit. Thanks.

Tim

DuffMan

iTrader: (1)

The MAC products use a ball + socket type joint, rather than flat flanges that bolt together. Because of this, a larger socket can fit over a stock-size ball, which is exactly what the replacement y-pipe does. The manifold collector is a ball type stock, and of course the MAC y-pipe is a socket type.

If you are worried about it being too much work, beleive me when I say it really is not. I did the same thing on my 91 RS, and was my first major project (i had only done various sensors, filters, etc.) and I was able to plow right through it, and frankly, if I were to do it again, it would be even faster (I finished in a day!)

I noticed you live in LA, and if you would be able to drive here (or maybe I could drive there with a friend) we could get the headers done. I've done exhaust on a few 3rd gens, some Fox mustangs, and LT1 cars. If you want to know what a hard exhaust is to install, just look under the hood of an LT1 car

lemme know if you want to work something about regarding an install (i can give you details of how we do it if you are interested)

eric

LAFireboyd

iTrader: (3)

Cool. Good to know. I figured it would fit, but I wanted to make sure before it was too late. And thanks for the offer, but I can probably do it without any problems. The "first time" has never stopped me before. It just wasn't something I'd planned on right now--mostly for financial reasons. My list of things to do keeps getting longer, so something's gotta go.

But even if for no other reason, doing the headers would be worth it just for the ease of installing new plugs/wires and O2 sensor at the same time, lol!

Thanks, Eric.

DuffMan

iTrader: (1)

yea, the headers really aren't that bad, let me just give you a few tips. For the driver side (right side if you are looking from the FRONT of the car) you can drop it in after you remove the valve cover. It will take some work, but trust me, it will go in. As far as the passenger side (left side from the front view) you could drop it in but you would have to remove your A/C and ****, so go from teh bottom up, but be sure to remove the starter. I spent easily 2 hours trying to drop it in, my neighbor came over and told me to remove the started and after moving the oil stick out of the way, it moved right into place

the GP looks like it will be in place for a while, so don't worry about being in too much of a hurry. However, if it looks like its going to take a while, e-mail me when you are ready to buy, and i'll see about getting you the good pricing anyway

eric

No AC worries--it's gone! I got a non-AC power steering pump bracket from my local dealer, and I can actually SEE my engine, lol. I hardly ever used the AC anyway. I only ordered it on the car cause my parents made me. Parents think "resale value." But I knew I'd never sell this car. And since I can NEVER buy a NEW one, this one will be in my will someday.

3rdgenstm

Does anyone know what type connection the replacement y pipe has at the cat? I ordered a new cat and cat back (all 'oem' replacements) and I may as well go ahead and change the ypipe. Will this one fit up to an 'oem replacement' cat? Everything I ordered is for 2 1/2" dia and the description here says the ypipe is 3". Is that correct or did I misunderstand something? The pic on their sight just shows the cat end as a slip fit, I guess.

Thanks!

DuffMan

iTrader: (1)

no, the y-pipe is 3" and is slip fit. I guess techincally you could make it mate with your 2.5" piping, but truthfully, there would not really be any gain from using stock headers, 3" -pipe, and then back to 2.5" cat-back

the only reason i could see for getting the MAC one would prolly be if the one you found was more expensive, but i'm sure you can find an OEM one for cheaper anyway (used at least)

eric

3rdgenstm

I was just looking to have it all new. This is the only 'oem replacement' that I have found with 2 bolt flanges. Does anyone know where I can get a mandrel bent stock type replacement? Is this something I will have to have bent by a muffler shop?
Thanks for the help.

DuffMan

iTrader: (1)

what happened to your old one that you can't reuse it?

3rdgenstm

The old one is still on the car, I just wanted to put a new one on there while I did the rest of it. It is old and nasty with 182k miles in it. No need to spend $300 on exhaust and have one nasty looking piece in the system.
thanks!

DuffMan

iTrader: (1)

oh ok, i see where you're coming from

my suggestion to you would be since you're gonna be under there anyway (bolting a new y-pipe on) you seriously may as well put on the headers. It is not that big of an install in these cars (again, LT1s and LS1s you have to sell your soul to get it in there) and you would defintely notice a SOTP gain. Also, it should still bolt up to your exhaust, but you may want to check with MAC on that just to be sure.

Thanks,
Eric

3rdgenstm

Oh I know it's not a big deal to put headers on. I had Edlebrock TES on my '92. I just didn't want to drop the 300 bones for that too right now. I thought about it, believe me. It would be easier to do it now though. Hmmmmm.... I got my other stuff today and the cat OD is 2 3/8". I could sleeve the cat to build up to the ID of the ypipe. I'm gonna do some more research. Let me know when this GP is definately gonna end. I'm not in a big hurry to do this. It's a little cold to lay on my back in the driveway for a Saturday!

DuffMan

iTrader: (1)

Haha, I understand about working out on the cold. Like I said, there is not a set date yet, who knows, they may continue to offer this indefintely, i really can't say. And no worries on the money issue, I think we ALL have the same problem of not having enough to do what we want/need to do

Anyway, my suggestion is to save my e-mail address, or something, and whenever you are ready in the future, just drop me an e-mail.

I am thinking about ordering the Cat-Back System, and I was wondering how that would sound with my 305 TBI. I am looking for a loud exhaust system. I was also considering the flowmaster American Thunder system. Any opinions on which sounds better and better performance?

DuffMan

iTrader: (1)

Well, the MAC exhaust IMO sounds great. Has a nice burble at idle, and really screams when you get on the throttle. People would always ask me what kind of exhaust I had on ther because no one had really heard that (I had a 305 TBI as well). Flowmaster sounds good, but frankly, everyone has it, which is why I chose MAC in the first place (I liked it so much that I paid full price when I had my old 91 RS!)

LAFireboyd

iTrader: (3)

Ahhhh, burble. Is that the technical term? I always wondered what that sound was called, lol. But at least the word burble somewhat imitates the sound. So how'd they come up with 'deep throaty' for mufflers, dare I ask, lol? I don't recall hearing anything that sounded like that when...

I should have $$$ this week, but I still haven't decided what I'm gonna buy. Unfortunately, it's looking more and more like it can only be the Y-pipe. But since that stock replacement Y is probably different than the header Y, it won't make much sense to buy the Y now if I plan to get the headers later. So as nice as the discount is, I might wait on all of it 'til another time. I just have too many more practical things to spend on besides the car.

For the car, it's kind of down to a trade-off between a new clutch(which I might HAVE to spend for) or the headers/Y-pipe(which is a luxury that I don't have to spend for). I've tried and tried to budget for both, but I just can't seem to find a way.

I hate it when I have to be practical!
