i just recently bought a used SPT catback exhaust system off a buddy. He has the original box with it, but no instructions (not that i need them ), but i bought it off of him for $200. Does that sound like a pretty good deal?. It was kinda a impulse buy i guess. Just wanted to know if $200 was a good deal, and it has about 10k miles on it, never used in salt or snow. Still has polished shine for the most part. Also how long will it take me to put this on? It's all bolt up right? It's going on a 05 wrx sedan (all stock). All feedback is very much appreciated!
