I was wandering what it was like... It seems to be cheap enough, but that too scares me. I've heard people say good and bad things about the Stillen and Greddy.. What do you all think??

 

I have the Courtesy muffler and b-pipe.

The main issue brought up with this setup is the "extension" piece that you have to use to attach the cat to the b-pipe. The piece is small bore and has an awful bend to it.

The muffler on the other hand is pretty nifty. It's a cannister design with two different tips available from Courtesy. One tip is the basic can, the other (that I have) has a "lip". Only problem I've had with the muffler is that it sits lower than the stock unit and is prone to getting scraped on ramps and such when I have a car full of friends....... Good sound IMHO.

Do a search on Courtesy Exhaust and you'll find more info.
