I read the posts for the groupbuy and honestly I can't see paying $700 for duals.
I found the piping from jcwhitney for under $100 (for the mandrel bends that are needed for duals).
So basiclly that dual in/ dual out cat sucks? Are there better brands of cats? Do I just need to make sure its super flow cats?
I found high flow cats on ebay for $50. Are these ok?
Bomz Cats or these?
Car Sound High Flow
