The Greddy Evo2 exhaust is the best fitting exhaust that I have seen. It will fit perfect everytime. You cant screw it up. You can get the Megan Racing to fit really bad and melt or discolor the bumper. It takes a lot to get them to fit just right. The Buschur system is loud and raspy unless you get the Magnaflow. They dont fit perfect, but you can make them fit decent. The Greddy Evo2 is the right length for the USDM Evo and it sounds very smooth and mellow. It may not make the most power out of a catback, but who knows, I dont know that it has been tested back to back with others. It does taper to about 68mm inside diameter at the cat which is about 2 mm less inside diameter than standard 3" O.D. tubing with standard wall thickness. So it doesnt lose that much in flow area. The resonator I have heard in the midpipe does go smaller than 3", but dont know how much that hurts performance, I do know it helps the resonation at highway cruising speeds. It looks very close to stock when installed because the muffler is tucked up nicely under behind the bumper. The muffler is very large in diameter but looks much smaller when installed.

I got mine for $495 shipped. I love it. I dont think I paid too much for mine. I think it was worth every penny. It fits so nicely, I dont have to worry about getting an exhaust bumper heat shield. How many cheaper exhausts dont need a heat shield to keep from melting the bumper.
