Catalytic converter and collector
Thanks for your input! I was only leaving the headers out until later because I didn't think they would help that much with a TBI engine under 250hp. But it sounds like they can definitely help. I was planning on doing them later, but might as well get them done now. Maybe just some stainless...- 94FSBlazer
