If it quits raining I'm going to get a clip of mine.

I'm looking into what might be quieter though. I liked the way it sounded back when it was a Catco high-flow cat, 2.5 I-pipe, and a dynomax 2.5in 2.5dual out muffler, but then I added the pacesetter headers.

Now I think it's too loud. Sounds great at idle and while cruising, but under acceleration it's annoying.

I found the dynomax single in/dual out super turbo muffler for $60, and I've heard the turbo mufflers are a little quieter, so I'm thinking about it.

I wish I had the money for those headers . Were they easy to install ?

Hum.....?......


thats different from whats been said and add on here....If you can get a sound clip that would be great...

I'll be waiting to hear from it...thanks again...

Ok. I had the camera too close on that bumper shot and overloaded the sound, but it was taking 3 tries to get a clip that the computer would download and it seemed like it was about to rain so I lived with it. Anyway, to me it's just a little on the loud side. I think there's some muffler or heat shield rattle in there too.

Was kinda hoping to get what it sounds like just cruising after accelerating, but it doesn't really show up. (and yes, I need new shocks.)

If I find something better for recording audio I might try it again. A mic hooked into the laptop might work better than my camera.

I don't know how to embed the video into a post either.

i got a flowmaster 80 series with a gutted cat, people always ask me what size V8 i got, i think it sounds really good for a v6

Did you check out my video ? I have a glasspack inplace of my cat and it sounds great .

pull the cat out and do what bird did...sounds great and I have that ready for my camaro


P.S. People I'm still looking and still reserching my muffler....LOL

Thanks for the complements and a gutted cat will sound different than a glasspack inplace of the cat .

Guys check out how this one sounds...

very agressive and good.

Flowmaster 80 series....


3.1 V6 Bird


http://www.youtube.com/watch?v=i7FtCBW1mwA

it will sound different for a certain time, eventually all the stuff will blow out of the glasspack and it will be a hollow tube just like a gutted cat

thats one of the reasons i bought my cherry bomb glasspack. lol it will get louder as i go lol

Hey 89, that's the same thing I wanted to do with my exhaust, I really like how it sounds on the video.
But how did you get the cherrybomb in where the cat is? The exhaust pipe hooks up with one of those 3 bolt things so I cant see using a u clamp.. Got a pic of the pack hooked up you could post?

Thanks , the glasspack is welded inplace of the cat it is longer so some of the pipe is cut off to run the glasspack .

Entrig00 that almost sounds exactly like mine .
91Camaro_RS the internalsnever come out of the GP they just loosen up to fill in the internal holes inthe GP to make it more like a piece of pipe.
big313rsboi you could mount your GP with the raised holes inside pointing away from the engine and it will be as loud as it will get out of the box because if you mount it with the raised holes faceing the engine you have to either bust the packing or let it wearin over time .

very nice....hum....

Many years ago I had a '79 Chevette and replaced the cat with a piece of pipe by takeing the cat off and useing another cat I had as a guide for how long to make it and cut the ends off one cat and welded them to the pipe and bolted the pipe with the cat ends back inplace and it sounded good with a stock replacement muffler with about 4in tailpipe . So you can run a gutted cat , length of pipe , or a GP to get the job done .

Damn wish you were here in Tucson, AZ lol


So far Flowmaster 80 series sounds like my option lol

I like them .

http://www.youtube.com/watch?v=UyvZq...om=PL&index=54

Damn another one for Magnaflow

i thought my v6 sounded good without a muffler
just a cat and 2 1/2 ( i think 2 1/2) all the way back.

I had mine that way for awhile when my muffler came off but I have a GP inplace of my cat . If I could have run my tips and duels without my muffler I would have . The stock pipe is 2 1/4 all the way to the muffler .

thats what mine is right now...and thats the reason for this thread


so far I have two in mind

Flowmaster 80 series and Magnaflow

Go with the 80 if you want a cheaper muffler , but if you don't care about price then go with the Magnaflow . IMO they both sound great .

Guys I'm still trying to decide but heres a very good question for my future muffler....


What size of piping do I go with from the Cata.?


3' I think would be to much for your V6....but I dont know


Any info on this ?


Thanks again guys

Stock is 2 1/4 and is fine but if you want to go larger I would go 2 1/2 .

Should I just go regular then? I mean how much of a difference would it?

I remember someone in here saying that we need the back pressure and all....

damn now I have to go back and read throu all these pages...lol

i have the dynomax dual on my 87 2.8 and it sounds very nice. it has i nice low pitch rumble to it. hard to tell its a v6

I'm still running 2 1/4 back into a 3in inlet muffler .

Alright guys I think one more week and I'm going to get my camaro a new exhaust....


I'll make sure to put before and after pic and sound clips for all.



for the mean time it came down to flowmaster 80 series and Magnaflow...


is it cheaper if I order the muffler from the companys that make them or throu like summit, jeggs...ect?

Thanks...

P.S. Bird thanks for hanging in there with me.

I wouuld check prices even at muffler shops and your local parts places and even check Ebay and Craigslist for used ones . entrig00 .

Maybe its just me but seems like people charge less putting in a

Flowmaster 80 series then a Magnaflow....crazy




Still looking guys and still getting qoutes on installing a new exhaust.


Cant find much on Craigslist.....

You do need backpressure, i just replace dthe old cat with a cherrybomb glasspack and it came loose the other day, so exhaust was getting out before the cherrybomb. it had NO low end and i didnt want to push it because i didn't want it to fall off more.
I think the cherrybomb made my car quieter overall, but the sound it makes is lower now. Just got some cheap muffler and thats the way it's gona stay untill that one rots and falls off.

I thought so. what do you mean when you say No Low end.....


Thanks K

He has no power on the bottom of the power curve but I bet he has plenty on up in the curve with an open exhaust .

ok I know this is a no no...or I think but when I was driving my car with no muffler what give me a different feel from when there was a muffler? What I mean is when I was driving the car to muffler places to get qoutes I notice that I couldnt flore it because it didnt want to pick up. I mean Id step on the gas and it didnt want to go...was that due to not having a muffler or would it be something else ?

Thanks bird....and bro you need to be over here in AZ lol

Yes no muffler kills the get up and go of the v6 as far as me coming to AZ you should come to TN it is very beutiful here in Pigeon Forge .

Great, I was afraid you would say that about the get up and go. Dam*t....TN would be a lot better then over here to hot.

So muffler has nothing to do with that....Great great great....I"ll PM you.

Yep, bird pretty much explained it for me. I'd hit the gas, the car would be loud as sh*t, but it took forever to get any speed.
I gotta say though, I'm very happy with the cat replaced with the cherrybomb. I dont feel any effect in the low end torque I always had and have gained a little in the 3Ks. It made my car quieter in general, but the sounds also lower, more of a rumble.
I had been planning this for a long time and when I saw Bird had done the same thing and heard his sound clip I went to it. So thank you.

so entrig00 did you get your exhaust done yet?

and does anyone know what a 3.4 with a 3500 top end swap would sound like with a punched out cat and flowmaster?

A 3.4 with 3500 topend should sound great with that exhaust . I think there is a video on youtube of one IIRC .

now if I could get my dad to get the zuk out of the garage and my car in there I would be happy, I need to find a 3.4 now lol.

Your best bet is to find a Pull -a - part and get one from a fourth gen with a 3.4 in it .

well looks like plan might have changed I might be putting a v8 in. does the front part of a firebird come off? aren't they unabodies or something?

The only parts on the front that come off are the hood , fenders , bumper , and k member . And yes they are unibody cars .

lol, I drove around like that for awhile when the muffler rusted and fell off while driving. I got more compliments for the sound of my car than I ever lol.

I have to get back under the car and tighten up all the bolts AND get this hole re-welded. Car sounds like crap right now. Sounds like a loud fart with a little whistle lol.

To get the v8 in, you just need to change motor mounts.

what about tranny mounts?

I used my v6 tranny mount (v6-> v8 700R4)

There's a nice guide in the motor swap section.
