I'd say yes, its stainless very high quality build and definitely a great sounding system oh and fyi for when i post the clip I'm not running a cat either. fyi you can normally get the price down using best offers on ebay.

What a great thread! Has anyone done a before and after dyno run with a stock L-98 with any of these catbacks?

magnaflow system on 305 tpi with dying fuel pump oh and no cat. sorry for the wait

i cant get that to work...

I can't either

that file wont play directly you have to save it to your computer open it then play the file inside.
for windows xp
right click on the link
select "save target as"
choose your desktop
after it saves the file on the desktop
go to the desktop if you double click on it, windows xp should be able to open it it should open similar to a regular window and show a media file inside.
let me know how you do.

(these instructions are assuming you are using win xp and internet explorer)

considering i'm not computer illiterate... The way you suggested would be the way I attempted to open the ile the first time. I dont think that you zipped the file correctly. Try posting it on you tube or another site like it and copy the link. It would be the easier way...

slow your roll my man i never suggested you were illiterate in any form or manor. i'm going to ask a moderator to post it in the sound clips section seeing as i've dl twice on two diff computers (with no prob) and apperantly one of the mods had no problem. don't take offense i don't know you like that and only provided a walk through in case.

nah dude.. its cool... i was just throwing my computer out the freakin window b/c it sucks and it didnt work like it should have... lol..

Heres a clip of my magnaflow. Stock motor, hedman shortys and Y Pipe.

Ok I am a true newbe. I just picked up my 1991 Z28 5.0 last Friday (had a 1990 RS new before it was taken by some a..) and have already ordered over $2000 worth of stuff (please don not tell the wife )

So I just ordered my Cat back Borla Exhaust, I am still running my Cat and can not change the headers just yet...

Is this going to take away from the quality of the exhaust?

BTW: I ordered the system from amazon.com they actually had the cheapest price I could find.. They display the wrong picture but I called and confirmed it is the correct part Borla 14888 Cat Back System $790 Free shipping..

wow are those borlas expensive.... i never was crazy about the sound either but i guess its adjustable so thats a plus.

no headers will cut off some of the sound but it should still sound ok without them. what i'd do if you want abit more tone is gut the stock cat converter or get a highflow unit. that will greatly improve the tone and sound levels

The sound is pretty kool. I happen to think the tone is just perfect.

Ok so who could tell me how do you adjust the sound?

your borla kit should have come with plates that you can put in the passenger side tail pipe right after the pipe comes over the axle and splits into the muffler. I believe there are three different plates, each have a different size hole through the middle. the bigger the hole the louder it is.

Great, I did not see those items in the kit!!!

so there is a flange on the passenger side tail pipe, right??

Yes, the flange is there. I called my buddy who put the exhaust in for me and after a few @#%$## he stated that he used the middle size....

Thanks for the info

I just picked up a 4th gen borla catback for cheap and got it hung today (not plumbed yet so I'm not sure how it's going to sound). I'm not big on polished stuff and I was a bit worried about the tips at first, but I think they came out subdued enough.. it's growing on me anyway. It seems like a good system if you can find one second-hand.. I certainly couldn't have afforded it new. Overall the 4th gen kit was a slight pain to retrofit, but all that needed to be done from a fabrication standpoint was to make a few hangers.

I have a 305 TPI stock everything. I want a nice deep sound for normal driving but when I step on it, I want it to really make some noise... any ideas on what would be best?

flowmaster with electronic cutouts

Hey guys, seeing as though this is a thread to help people find cat back clips, I just thought I'd post the link to a vid of my 91' Firebird 305 tbi with the 3" Edelbrock SDT cat back. Everything is completely stock except for the cat back.


http://youtube.com/watch?v=x87vnJuq7vE

What muffler did you run??? I'm curious as well, I have the same idea as 87irocu has and forget the bullet and run a chambered muffler.

was the sound a piece of crap too? have you replaced the flowmaster with something better? let me know, pls. i wanna know which brand to get for my 91 RS and i'm so undecided.

Hers a clip of my magnaflow. 305 TPI hedman shorties with Y-pipe, no cat.

I provided updated clips of my GMMG exhaust to a mod of this board but it doesnt look like the post has been updated.

ive been hearing people talking bad about edelbrock catback and thought id drop in with a vid of my edelbrock SDT 3" setup. yes, it is a worn out 305......

Here is a video of 305 TPI hedman long tube headers, 3" single into 80 series flowmaster. And there is no cat

How about this one, the only one I found for a 92 firebird formula 305 tbi.

I also read somewhere that I should change my cat converter, is it possible to upgrade it or should it be stock?

If you need to be emissions legal you can go with a high flow cat and still pass.

Yes, if you use the rest of the tricks in the smog passing book

I'm in the market for a cat back on my 82 Z. Actually I'm going to revamp the entire exhaust system, the 2 1/2 isnt big enough I'm getting too much back pressure and I want to go with a 1 3/4 primary LT header with a 3" collector but I gotta find a Y pipe and test pipe, right now I'm running no muffler, n cat just the original 2 1/2 that came on the car (had the 2 mufflers with cross pipe that were rotted out cant argue with a free fix). Ilove the deep tone of my straight pipe but it get that annooying crackily sound at high RPM. The car has a 385 stroker, healthy cam and an 800DP carb any idea's, suggestions?

I have a 1989 camaro rs 5.0 305 tbi; would this still work even though it says 5.7?
http://www.magnaflow.com/02product/s...zone=all&id=95
(the 5.0 and 5.7 don't look any different and there sizes are the same)

I heard lots of good reports of magnaflow so i think i might go with these! I just want an opinion or two before i buy. ( i haven't seen any vids on 305 tbi camaros with magnaflow exhaust thats why i hesitated to buy..)

regards,
Timinsk

Iam surprised that Pypes was left out. I had the edelbrock system on my 305. Very disappointing, none the less. So I decided to get a pypes violator muffler put in place of the edelbrock one. Boy did it make a difference. They make catbacks mostly for mustangs, but they also make a few for camaros. Its sounds really good, super loud too.

sounds like this : http://www.youtube.com/watch?v=NfHi3BlrSQU

Actualy yes they do now, they make a 3 1/2" that I am considering

I was told that the Flowmaster #17233 would not work on the "LO3" and I would need to purchase #17234. Is this correct?

The 17234 is a 2.5" and the 17233 is a 3" exhaust system

Thanks,
Jack

Iv had the edelbrock catback W/ the RPM muffler on my camaro. with
the Lingenfelter 383. gess a few Guys dont Like it.. i always did.
at WOT it sounded like a prostock car. and on mine it was running 11:70
and 12:00's with street tires.. but then thats a car with a bit more power then most..

Any suggestions??

How about this one?

The video I've posted below was originally in post #2 on page 1, entitled, "Random Tech Clip #2," but that link is not good anymore. So here's a new link:

http://s61.photobucket.com/albums/h5...yExhaust1a.mp4

The engine is original, not-rebuilt, still-stock LB9 305 TPI with exhaust manifolds. But from the manifolds: MAC stock-replacement mandrel-bent y-pipe(2-1/2" downpipes into a 3" collector to the cat); Random Technology 3" cat; Random Technology 3" exhaust system(3" I-pipe; 3" in/dual 3" out straight-through muffler; dual 3" angle-cut tail pipes).

From start-up in the video, the engine runs through its fast idle cycle(you'll hear it idle down at the 34-second mark), then I rev it a couple of times and run it up to about 4000 rpms. The camera is off-center behind the car, making the exhaust look like it isn't centered, but it is.

I had no idea what to expect, sound-wise, from this exhaust system, but its size and design made sense, and I liked its simplicity too. So I got it, and I'm glad I did. I love it. Its sound resembles a 4thgen Corsa exhaust system. It might be a little too civil-sounding for most people, but driving down the road, it turns heads; at smog tests, it attracts a crowd; and at a slow cruise in 2nd gear through neighborhoods and parking lots, it sets-off car alarms. And when I'm on the freeway, its sound reflecting off the concrete divider sounds great. I never had that with the stock exhaust.

It seems like nobody has ever heard a Mac Cat back on a 100% stock thirdgen,

i ordered

Mac P/N: TKC691

I have a Bone stock 89 RS L03

only things done to the motor are regular maintenance and an Open element

stock manifolds, stock Y ,and stock Cat will stay and the Mac catback will be put on, then i will take a video of Idle and Rev and post it here for everybody to see and hear

ive heard this system on a 350 camaro and a 305 TPI Bird but both of those were far from stock and had full exhaust, i just want everybody to hear what a stock 305 TBI will sound like with this cat back

..........
and if anybody has a clip like i am describing please post it, i would like to know kind of what it will sound like before i get it here lol

In searches, I've found several guys using MAC headers and liking them, but only a couple of guys who mentioned they had the MAC exhaust system, also giving it good reviews. But I've found no video clips of it.

IIRC, a few years ago, the History Channel show, Full Throttle, mildly built a couple of '88 IROCs, and they installed the MAC exhaust system on one of them, maybe both of them. So if you can find the show, maybe online, there's your example.

you've found exactly what i have lol, guys say they like Mac, but nobody has a video of a stock 305 with the exhaust

and actually i started a thread on here a few weeks ago about that show(i didnt know it was full throttle when i posted the tread) and ended up buying it off ebay for 1.99, i know they put exhaust on both the irocs but didnt know if it was mac or not, i love the sound of the Mac catback, but in the show it was on supercharged 350's and the ones ive heard in person were on heavily modded engines with full exhaust

i will be doing it with a bone stock RS and the catback will be the only exhast the car gets will be interesting to hear what it sounds like

thanks for looking out and posting what you've found

does this fit the 5.7TPI ?
Summit only shows 5.0
I figure they are the same configuration
I only need confirmation
and isn't that too cheap for a catback
especially with a $75 rebate?
also which dynomax ultra flow cat back is
correct for the 91 L98? ...got sound?

Banks:

I've only seen banks on a couple thirdgens, so it's definetly got points for the uniqueness factor!

i have a 92 firebird 3.1 5 speed and my pipe fell off so now its just my manifolds going into a rusted out cat and then nothing. its way to loud and sounds like sh**. if anyone has a recomendation on a good mean sounding exhuast for my 3.1 please share

Magnaflow just came out with a cat back system that fits my 88 camaro perfectly. Great sound. I have a modified 350 cu inl. (now 355) Edelbrock aluminium 202 heads, high flow water pump and headers, crane roller rockes, borch injectors, MSD ingition) so it will sound somewhat different on a stock engine.
