3rd Gen Exhaust Size 2.5 vs 3”

Tuning is the only way to ensure the oversized pipe doesn’t negatively impact your performance. If all you want is a better sound changing just the muffler or going with a TRD exhaust may be your best bet.

funny how people have found 3” to be “too large”. We run 3” on 2.5L K24 Honda motors and with tuning the produce power across the entire rpm range over a 2.5” pipe or even smaller. But, we can tune for it.
