The quality of the Spintech components is good. The x-pipe, including the Dr. Gas crossover, is stainless steel. The cats did prove to be inadequate for the 4.6 motor, a known problem. I contacted the Spintech distributor near me about my SES light coming on despite me having catalytic converters, and he suggested putting MIL eliminators on. I did, and I haven't had a problem since. I don't know if the car will pass the smog test, but I'll cross that bridge when I come to it.
The fitment of the Spintech parts did require a little work to make it look right, such as trimming a bit off the tailpipes where they enter the muffler. The x-pipe still hangs a little low for my taste, but I could have tried to heat it up and adjust it a little. I didn't contact Spintech about this, so I can't blame them. I'm pretty happy with the way it fits now.
I bought my exhaust in June 2002, and it's been great since then. It's about to go through its second salt-ridden Chicago winter! At the time I bought my exhaust, Spintech was unable to manufacture stainless steel tailpipes. I have aluminized steel pipes with polished stainless tips. I haven't had a problem with rust, even in an area where I accidentally scraped the coating during installation. You should check with them now to see if they are manufacturing stainless steel tailpipes. The aluminized steel seems fine so far, but I may not be as picky as some of you. Keep in mind, it's only the tailpipes from the muffler to the tips that are aluminized; everything else (x-pipe, mufflers, flow tubes, tips) is stainless steel.
If I were you, I'd invest in some stainless steel clamps instead of using the cheapo ones. I chose not to weld my system together (it fits fine and doesn't leak), but it sucks to put bare steel clamps on a nice stainless system. The clamps rust after a little while and look like garbage.
I hope this answers your questions...I think I already addressed the sound quality in my previous posting. If not, then I'll say that I really like the way it sounds. I wish I could follow my car sometimes, because it sounds even better outside the car than it does on the inside...
