Well I just happened to stumble on the Pypes vendor at Carlisle the other week and it was too tempting so I bought the midpipe. After 5 hours on two different days along with 7 stitches on my friend's head it was on the car. As far as the sound goes, I love it. It sounds really close to Wyotechs car which makes me pretty excited and I don't think there is much difference between a two valve and four valve SLP exhaust. :banana: Oh, and it's as loud as an offroad H and Flows and my check engine light is not on so I'm happy. What do you guys think of it? The tell tale signs of a battle with the 50 pound midpipe falling on my friend's head.
