Well, if you go with the pre '97 setup it comes out to $35.55. However, if you go with the '97-on setup, it comes out to $19.90. I don't think #'s 10&11 are used on the the post '97 setup, perhaps they're incorporated in part#1 or 4? I was just suggesting new because these parts are usually pretty rusty and damaged due to heat and elements. I know when I removed my stock exhaust, a few of the bolts snapped, threads pulled out of the nuts etc. Either way, do what you like. I'd never buy/install used exhaust hardware on my car when I can spend an extra 10-20 bucks for new stuff, but that's just me. Now if it were the actual cat itself, heck yeah I'd pick up a used one before spending $1800
