Well my question is what is the stock pipe diameter on a 97 SE? Just wondering so I get the right inlet sized muffler and dont have to change the pipe.

Four more questions:
Do you mean 90 degree bends?
Can I just cut the pipes to size after I have them bent?
How much will the bends cost?
Which size inlets and outlets does your Flowmaster 80 have?

BTW...if that'* your car in the video "exhaustlong" thats the exact sound I'm going for.

your piping is 2.25inches...and i believe the camaro/firebird muffler is 2.5...they can make it work though if you insist on the dual outlets...

my exhaust is very subtle...heres a link to some sound clips from my muffler

Is that a single pipe? I like the sound but I'd prefer to get a dual set up going. How do you adapt a 2.25 pipe to work witha 2.5? I don't want to have a shop install this, I want to do it myself.

How would I go about adapting the 2.25" to fit in the 2.5"? I have access to welders, so that'* not a problem. Thanks

you could use a reducer, i dont know where you would find one exactly, im looking for some now and the only one ive found so far is a 3>2.5 one, look for intercooler accessories and stuff like that....you might also be able to take a little piece of 2.25 pipe and expand it out to 2.5, but usually exhaust shops are the only ones who have those fancy pipe expanders.

you can also gut out the stock airbox for a minor increase....and it will be VERY minor, mostly gutting the airbox adds a lot to the sound of the engine more than anything...below are the pics of mine, it is very loud on cold start....i cant hear my intake an easy couple hundred feet away on cold start...and i wish i was joking, it settles down once it warms up though...in the pics the "front" section is the one closest to you as youre standing in front of the car.

rear portion of front section, removed all baffles

rear section

and yes i dont like the dust inside the rear portion....thats not good, but its just SOOO dusty around here i dont think any filter can keep up, and yes i hosed off everything really good before putting it back together.

What type of pipe should I buy, or would it just be best to take all of the stuff to a meineke or somewhere like that and have them install it?

Has anybody sugested a pair of headers? I'm not sure if they make some for these cars, but they should, since the FWD platform has been arounds since 85.

ITs definitly a good idea to add headers, add more flow to the engine, gaining in quickness and performance. Not sure if you can run dual pipes out, as ther are claerance and space problems, but you should be able to get it done.

The reason I mentioned headers, is the pipes for the exhaust run over the transmission bellhousing, and connect up with the other bank of cylinders. It is this that adds to increasing backpressure, and restricting the engine flow. The reason GM does this, is its cheaper to cast the manifolds, and I think its to reduce noise.

If you go this route, it will probably end up costing you alot, especially if you have a muffler shop do the mods, but the performance, and the sound of it may be worth it.

I have never done this before, and have no idea what it will sound like, nor by how much power gains are, so comments and critisim are welcome.
