dont know about you guys but i paid $350 bucks for a duel 3" exhaust with mandrel bent x-pipe from TTI. Threw it in myself in a weekend. I could not touch that price at a shop. your not gonna find many shops doing mandrel bends on 2 1/2" or 3". i got quotes of up to $1000 on my system. Every car i build from now on will be getting a TTI exhaust.
