if you want a cheap exhaust a 4" goto the classifieds and try to get the downpipe and muffler! I bought a downpipe on ebay, two 4 foot pieces of straight pipe from summit and a muffler and tailpipe from advance auto and installed it in about an hour. The straight pipe is about 16 inches too long but everything else went together like a breeze. a local muffler shop welded the joints and it sounds good! save some money for other performance mods!

 

Better yet, skip the muffler and tailpipe, and just run a straight section back from the downpipe. Thats what I'm running...and it sounds sweeeet. I get thumb-up from most people, except the ricer crowd and old ladies who i scare when i go by them with my foot in it and my exhaust coming out near their window. I can't wait until I have SMOKE to throw at them!!!

 

More fuel and pod injectors make for lots of smoke!
