Had Stillen’s Exhaust installed on Friday 4/12/02 and fell in love with the over all sound. Performance was hard to measure and was scheduled for a Dyno but the shop I was supposed to go to went down for repairs. While I was having the mufflers installed I asked the shop lead tech about cat backs. He has allot of experience with high performance setup and said there would be a greatly enhance sound as well as a greater overall performance with the elimination of the crush pipe section just in front of the y pipe. My next question was about clearance and Mendel bent tubing. He was sure that with a slight Mendel bend just before the current crush pipe location would yield the same clearance and would not lower the pipe any closer to the ground. I gave him the thumbs up and put my baby in this pass Friday to have the cutback completed. $175.00 and 45 minutes later she was pushed off the lift and I could not believe the sound out of her. It is absolutely fantastic . Still can’t claim any performance boost but it feels a little different. With out a doubt the single most bang for the bucks you can do to your car.
