2" to 3" exhaust... Worth it?
Just going from 2 inch to 2.5 inch will increase the flow by two-thirds, and that's not even taking into consideration crimp bent vs. mandrel bent. Horsepower potential goes from less than 300 for a 2 inch dual exhaust to over 450 for 2.5 inch setup. Then there's a three inch system for the big boys.
