Guys since we have 2.25 inch piping for stock why do some people with our cars still get 2.25. What would be better 2.25 or 2.5??? Keeping in mind of course not to lose to much Low - End.

Thanx guys..

It depends on the setup they go with. If you're running true duals, use 2.25", anything larger with that setup on an N/A would reduce too much back pressure. Some guys who have gutted their main cat and removed the extraneous resonators on their stock exhaust say that reduces too much backpressure, and gives them a big loss in low end torque. Personally, I think the big restriction in the N/A exhuast is the stock downtubes. That,, and the 16 extra resonators most seem to have collecting on the main exhaust pipe...
