Hi everybody

My s2000 had DC Sports Header and Comptech cat back system. I want to remove catalytic converter and install a test pipe. What dimensions it should have?? 2,25 / 2,25 or 2,5 / 2,5 inch?? I can't find what size is at header and cat back.

thanks for answers!!

 

Berk 63mm should work fine. It has the anti fouler built in so no need to worry about a cel

 

Find the size of your exhaust and run a test-pipe of the same size.
