Ok..so the car i just picked up is a 93 del sol, d16z6 turbo..current exhaust is custom 3" piping, not sure if I like it or not.. I was wondering if you guys could give me some information on exhausts, or if anyone has one for sale? I guess i'm wondering if its ok to put a 2.5" catback or something, or if i need something bigger? Running street tuned on 8 psi right now, will be getting dyno-tuned at 15psi, so looking for something that would support that. Any help would be great, thanks!
