Exhaust is shot on my car..Looking for a good exhaust system and cat.. Anyone have suggestions or even videos of them..thanks

 

I have something custom on order right now and am going to try and retrofit into the car. This muffler is going to take the place of the I-pipe which is the exhaust section that runs parallel to the driveshaft. This will allow for less tail weight on the car and an overall shorter exhaust path exit to the rear of the car with a single 2.5" hidden turndown.

when you get this could you post a sound clip...Looking for something that is deep sounding ..

 

FLOWMASTER awesome sound until it gets to 3000, but they are all like that

 

I had that when I had my V6 in the car, and just as you said, it sounded really good, until the motor got up in the powerband, after that, kind of sounded like a fart can.

 

My Flowmaster 80 sounds best up above 4k. I have said it before and will say it again its all what size dual exits you use and everyonegoes too large with dual 2 1/2". I have 1.75" dual exits. Sounds great above 4K, not just good. I am only changing thigs reducing weight and shortening the exit path. Besides, I need a new cat and am about to put the headers on the car so I am changing the exhaust temporarly to fit the 2.8 still with the PF&E headers. I am just using mild steel mandrels for now.

Later down the road I will change to an entire SS system with the 3.5L motor. I want to experiment with this exhaust routing and fit to see how I like the noise and ground clearance. Then indue time I will go to SS if this works and I will match the size to the final new engine outcome.

 

I think Flowmaster sounds the best by far of any muffler I have heard on a 2.8.

 

i've got an 80 series with headers and no cat before it. it sounds good on low end. i'm wanting to put a glass pack or round muffler in the i-pipe also but i'm going to keep the flowmaster too. just trying to quit it down a bit.

 

when i get to round 4k it sounds like a fart can but just idle it sounds hella nice

 

So if i get the 80 seris muffler what exhaust system should i order? thanks

 

run a 2.5" i-pipe. aka...2.5" inlet and dean (rtfc) will suggest smaller than 2" tailpipes.

 

Ok so with a 3.4 if I get one around here and drop it in.
Pace setter headers
No cat

What size piping and muffler should I be using to make it sound the ebst all around, I drive hard so I want something either muscle sounding or just quiet.

I was thinking maybe FLowmaster 40 but then it would sound liek **** up in high end
Then i was thinking FLowmaster 80 and it would probably be the same
So I was then thinking maybe generic then I could throw a new electronicly controlled cutout on the new Ypipe and if I need flow that the muffler wasn't providing just open the cutout.

Was thinking baout 2.5" the whole way back, 3" seems to big for a small displacement engine.
Or should I go with 2.25?


Not thread jacking but we all talking about the same **** so why not add to it

 

Well after doin some reading on other boards and listening to some clips i fouind that magna flow sounds awsome..http://www.magnaflow.com/04sound/domestic/camarod.htm ..there is a sound clip but im gonna need to figure a way out to make it work so any ideas i saw that someone earlier had posted about magna flow n was wondering how they were doin it and what they had to custom order

 

Thats a V8 in that Magnaflow clip, yours will not sound like that.

I just sent you an E-mail

I'd go 2.5, unless your 3.4 will be internally modified. Unless you are changing the layout of the stock system, the 80 Series Flowmaster is the one you want. To me any of the mufflers that use a chambered design (Flowmaster, Hooker, Spintech) sound better on a small motor than any of the ones with packing (Dynomax, Magnaflow, etc). They're fine for toning down a V8 car, but tend to muffle a 6 a little too much to me.

 

Layout will be the same, this engine won't be internally modified but I may pick up a block that needs a rebuild and go all out on it over winter.

 

Does flowmaster make the whole exhaust system from the cat back or just the muffler?

 

dynomax super turbo catback best sounding i ever heard doesnt sound like a v8 at 3500+ but it sounds better than flowmaster at high rpms about the same at idle. And its cheaper its like 159.99 for the catback

 

What about just glass packs? I was thinking of doing a glasspack in place of the muffler then have turn downs right behind the tires. Even with the aftermarket I got on there the tips still scrap when I come into the driveway.

 

i have a dynomax super turbo muffler and 2 1/2 in dual tails and it sounds pretty nice all around. deep growl down low and not to whiny when it gets up around 4k. my pacesetter headers were delivered today and ill get them installed on monday. cant wait for that. better sound, better flow and get rid of the damn exhaust leak at the manifold. three birds with one semi-expensive stone.

 

How difficult is it to install those if the original manifolds have never ever been removed?

 

ill let the mechanic figure that out as i dont have the tools. plus i dont want to risk snapping off a bolt in the head.

 

I got the tools, I just don't want to deal with a broken bolt like you said so if there is no......somewhat easy way to remove the bolts then I'll bring it to a shop.

 

Well you can spray them with penetrating lube, let it sit for a day, then do it, that will probably be about as much they will do. They might heat it up and try but if it breaks for them, they doing the same thing you are, but your paying them to do it and not yourself.

 

Heard an Edelbrock on a V-6 S-10, it made it sound close to a small V-8. Nice low growl. Kind of a burbley pulsing idle.

 

Here's my exhaust- http://www.geocities.com/tomp_3rdgen/exhaustclips.html

 

got the pacesetters on monday and took the poor guy all day to get them on. 4 bolts snapped off in the heads before he even touched em and one bolt missing. took it down to get welded where the left collector goes to the y-pipe and the y-pipe enters the cat. smoother and louder. mechanic that installed them said it sounds like i have a nice cam in it due to the lope of the idle. im not sure cuz i just bought the car in september and dont know what was doen to it beforehand. not a whole lot of noticeable power gains but much tighter throttle response and a nicer sound. sounds close to the 5.0 i had in my old 87 formula.

 

86bluebird...we're gonna have to meet up sometime! when i heard that you were getting those headers, i thought that we should meet up after you install them. so....hopefully soon we can.

 

am91 are you thinking that he is me? i know you and i were talking abou meeting up, but right now it is looking like not til after november, the check from uncle sam still isn't here and i have been having a hard time getting money together til the check comes in for all my mods, though they are slowly coming. i am saving like 600 every month, but that is only good for one thing at a time like you know. ked should be sending out my headers next week, so hopefully i will have them on the car by the first, with the new exhaust on shortly after that. car is gonna be parked around the 3rd when i do it. i think that i am gonna pull the engine when put the headers on so i can get to them studs more easily to drill out the old broken ones. you know how that goes with broken studs. only once did i not break a stud while removing a set of exhaust manifolds or headers for that matter, and that was on a 410 sprint car of all things!

 

i had a hollowed cat to 2.5in pipe into flowmaster 40 series muffler with 2.5in tail pipes into y tips with a 1.75 diameter each. It souded great, everyone thought my car was a z28 when they heard it.

My new camaro is going to have hooker 2.5in cat back system.

 

no, i meant him. he's actually closer to where i live than you are. you and i (87blue) will have to meet up to. but, i want to see 86blue's headers and all.

 

am91, we had talked previously about using my car to test your new intake on a basically stock car. id like to check out all uve done to ur camaro. sounds like an impressive car.

 

oh that's right, you were looking at the pacesetters, werent you.
i just talked to the guys from super six, it runs about 800 for our heads, but we supply the core. i think that i am gonna do it, just for the better flow and more Power!!!!!!!!

 

do theirs look anything like these?

 

lemme guess, you did those yourself? or did you do what i am gonna do and have them do them for you.

 

i did them myself.

 

nice work, i am assuming that they flow better than the super six motorsports!

 

I have the 80s series flowmaster on my 3.1 and it doesn't sound like a fartcan/***** in any form of the word... I've never met someone who thought I had a v6 before... unless they tried to race me.

when you rev the motor it still sounds strong... left and right people try and race me, and I never do, because I'd lose... still fun though.

 

gut the cat and drop a glasspack in place of the muffler.

 

My exhaust splits right after the axle and each tube goes in a glasspack and out throught chrome tips. Sounds good to 3,000rpm and looks good.

 

Mine don't sound good until about 2500 and up.......and gurgles at idle.

 

I have something up my sleeve right now and have changed the muffler positions from what I first posted. I ended up using the Magnaflow muffler up top in the position of the catalytic convertor(when I am not in need of the Catalytic convertor for smog test requirements- and replaced it with the magnaflow due to the catalytic convertor somewhat acting as a muffler itself. A straight pipe would make the car much louder so I used this instead)

Next, I have custom ordered a StainlessWorks smooth tube muffler in a custom length. Scott there quoted me $159 for a custom made 32" long straight through baffled 2 1/2" core muffler with 2 1/2" inlet & outet and a 3 1/2" outer body that is 28" long.
the stainless steel muffler is also being highly polished finish for that price. It'll be here in a few weeks.

In conclusion, I plan to use both the magnaflow(in the cat position) and the StainlessWorks( in the I-pipe position) together with nothing behind the rear axle but the tail pipe exit into a single 2.5" turndown. Just as strainght and short of a path to the rear of the car as possible with maximum flow through mufflers that will hopefully not be too loud- well see. 32" is as long as I can possibly have the I-pipe muffler made in order to make it fit. Anything longer won't work. However- the longer the quieter.

edit: Here's what the StainlessWorks one looks like, but the one I ordered is a custom length

I have always hated the way these cars look with that bulky crappy looking muffler up under the rear of the car. Now I will not have anything hindering the veiw of my trick suspension and plus the *** end of the car will be much lighter without all that heavy bulky exhaust back there- better for handling.

 

Wouldn't you want the rear of the car to roughly equal the front of the car, weight-wise? Seems that this will only make the car want to nosedive even more than stock... Just sayin'

 

Car doesn't nosedive at all. You guys have about 475lb springs and normal everyday street vavled shocks and struts, I run aprox 800lb springs up front, a progessive rate setup in the rear and setting that allow for minor squat under braking and cornering in the rear to reduce rear to front weight transfer, and a lower rear roll center to begin with than factory cars.

It has very minor to do with corner balance, it has major to do with polar weight (weight further away from the CG "center of gravity" of the car) Its like spinning and stopping that spinning rotation of your body with your arms out extended as compared to your arms next to your body. Centering the heavy muffler weight into the underneath CG position and lower helps transitioning agility. The nose of my car is already extremely light thanks to the V6- thats why I wanted to build a V6 Camaro. The extent of what I have already done to this car, these little things are noticibly felt unlike if the car were stock suspension. You would have to ride in the car to understand the vast diference between this and how it was stock. To add to this, the local guys around me were talking smack and taking offence to what I have always boasted about how this car is agile due to the V6 and the radical suspension & brakes setup I built into it- until they actually experienced it first hand t the local autox track. They will all tell you you can not understand until you see or feel it in action- it turns circles on any heavier V8 car.

I just have to skilss and knowledge to make appropriate changes to the car when new parts are needed and added, then tweak the proper setting to fine adjust any changes. My suspension is completely adjustable everywhere, unlike factory parts.

 

So when the hell do I get to ride in this beast!?

 

Anytime. Its not a beast though, not hardly near enough power to be considered a beast. Its more like a fine violin, you have to take care and percision with it.

 

so you think that if you spent the same amount of money in a v8 that it wouldn't handle nearly as good as the v6?

 

basically. its hard to make v8s handle as good. not impossible, but harder.

 

a turbo'd 3.4 will full suspension, vs a modded v8 would eat it i believe.

gotta love the weight transfer of the v6

 

1st off, even the LS1 aluminum block and heads is heavier than the little 60* V6's. Not by much but still heavier. But most importantly, the V8 LS1 has its centered motor weight more forward in the engine bay over the nose of the car. Now with a fiberglass hood, aluminum bumper insert, fiberglass fenders and a few things deleted like the AC then you are talking the same performance values in transitioning.

However, my car does all that while retaining ALL creature comforts like cruise control, AC, steel body parts for safety inpact of a collision, steel body parts for chassis stiffness(for handiling) and the most important part of I personally feel makes my car very tight and responsive is my two custom lateral braces which the front one further boxing the steering box & K-member can not be used on a V8 engine car.
