Does anyone know where I can find a 3 inch Intermediate pipe? From cat to muffler without having to buy a whole new cat back.

Summit also has a 3" over-axle too. Or you can get it all from Rock Auto for a little cheaper.'99 Camaro

Re: 3 inch I pipe
For a full catback, you'll also want a bigger diameter S-pipe. Not many sell them, but you can get a U-bend pipe and cut it in half, turn one side, then weld. Here's an old but good thread about it. There are also a few good threads with more info and links, but you might have to search a little more for those.

Re: 3 inch I pipe
With the mods you have listed on your users page, a 2.5 I pipe will do just fine. The factory 2.25" pipe has an area of 3.97 square inches. A 2.5" pipe has an area of 4.90 sq in. The 2.5" pipe can flow nearly 25% more than the 2.25" pipe.
A small change in diameter is a big change in area. Going to a 3" pipe is not going to buy much if any more performance than a 2.5" for your mods.

Re: 3 inch I pipe
Thanks, ill probably start this when it gets a little warmer out. Hopefully go with a nice 3 inch cat too. Have any of you guys bought that magnaflow carsound of of GVperformance? I think its like $70. The guy at the perf shop said he would charge me like 300, so i figured id just do it myself cause im def not spending that much money for a high flow cat.
