The quality is great on these things, I just recieved the random technology cat converter this evening and i'll be installing it tomorrow most likely. By the way I bought it from www.racesearch.com and used a coupon code "deal2" so with the stainless steel install kit(bolts, nuts, locking washers, gaskets) it came to about 180. Obviously don't know quite yet how it performs, but i'll know soon enough! Much smaller than stock and the honeycomb is tighter(smaller) I might put on the pacesetter catback while i'm @ it, but I like the sound of my exhaust so much now i'm not sure if I wan't to do it until I get another muffler for it. Laterz peeps!
