This is a flowmaster muffler and tail pipes for a camaro or firebird 82-92. i found it for sale pretty cheap and was wondering if I should get it...

My question is ...would it fit on my 2.8l firebird...intake pipe is 2.5 inches... (I dont know how big is the stock one)

 

Any competent muffler shop should be able to fit that onto your car and hook it up. It will definitely make the car sound better, but don't expect a whole lot of HP gain. You will probably get a few ponies, but nothing more than about 5 or so most likely.

Is this just the muffler and exhaust pipes, or is it the entire cat-back system? How much is it going to cost you? If you can get it real cheap, then I'd say go for it.

 

the look and sound should be worth it alone. a few extra ponies wouldn't hurt though. should fit right on.

 

just whats in the picture...i have heard that if the size of the inlet is too big (this one is 2.5 inches) you can loose back pressure and therefor lose power...instead of gaining any...cost about $40

I am just looking to improve the sound on my car...not really care about gining HP...but dont wanna lose any either
----------
how big is the stock inlet?? do you know
dont want to buy it ...if i am not going to use it

 

The stock pipe is 2 1/4inch. You could buy a Dynomax 2.5inch I-pipe and everything will bolt right on...although an exhaust shop can easily get that to work with the pipe you have.

2.5 is a good pipe size for a V6...3 is a bit overkill for these engines though.

 

I have that same exhaust.. 2.5" all the way through (no cat) with 3" tips.. to those who aren't too saavy they think it sounds like a v8.. your average wrencher.. usually a large v6 (4.3) and they best part is their reaction when you tell them its a 2.8 lol

not to thread jack.. but would there be any benefit adding a set of headers?

 

yea, you won't lose as much exhaust velocity and it'll sound better. on the down side they ad a lot of heat to the engine bay because the material is much thinner.

 

For $40 I'd get it and have a muffler shop weld it onto your stock pipe. It will sound good, and you won't lose anything. It will probably cost you another $40 or so for a good muffler shop to weld it in and hook it all up.

Back pressure does not make any HP, it only eats it (unless you are running a turbo). What people are talking about is if you use too large an exhaust, then your exhaust Velocity and temp can drop sharply and cause you to loose low end torque. With your system having the stock Cat and pipe from there back over your axle, you won't loose anything. Your car will sound so much better, and you will not notice any loss. Maybe a slight gain, but that would be about it.

 

For the price, you can't go wrong. You can either have a muffler shop weld the muffler in place or you may be able to source the proper "adapter" pipe (2 1/4 to 2 1/2") to connect the stock pipe to the muffler. With a couple of muffler clamps, you're good to go.

Also, I believe if you do a search, you'll find a thread with sound clips of various mufflers and what the sound is like. But, as said above, for $40, you can't go wrong.

Also, if you have decided to go with the pacesetter headers and the Flowmaster muffler to open up the back end, consider a CAI for the front of the engine.

"Breathing" and "Exhaling" are two limitations to these cars.

 

whats a CAI?

 

Where can i get a Cold air intake for the 2.8l??
I have never seen it? a lot of people recommend making your own...but idk
I have seen some for the 3.1...but not for the 2.8

 

I have never heard of buying a CAI for our cars. I can't recall if you have a Camaro or Firebird. Camaro's have a dual snorkel set-up that can be used. The Firebirds require some more imaginative work.

I have a pic of what I did in the thread (I can't upload the picture again ), so you'll have to look at the thread.

Kind of crude to start with, but it works. My next step is to relocate the sensors (MAF included) so that I can take advantage of the gap between the rad and the rad support on the driver's side. This will allow me to put the air filter just in front of the rad and slightly to the side - sort of like the Bank's turbos.

 

about how much $$ did that intake run you?
looks pretty good...got the steps and how to make one for myself?
