I put the exhaust on about 2 years ago. it was holding up just fine. when i put it on, i was running a stock catalyitic converter and stock manifolds. when i put the headers and hi flow on, i did have to turn up the stereo a bit if i had the window down. other than that, it wasn't that loud. i really liked how easy it was to install, and like i said, mine was still in good condition, even with 25,000 miles on it. i was thinking about pulling it off of my white truck and scavenging parts from it to make a custom exhaust for the new t-100, but i think im just going to buy a kit because of the fact that i'm a little to lazy right now lol <img src="/forums/images/graemlins/lol.gif" alt="" />
