Hey guys, i dont know much about exhaust test pipes and what will fit with my application.

I have a 60mm (2.25 in) apexi n1 cat back, and I just got an RMF Narrow 63.5 (2.5 in) header.

I dont have a test pipe or cat that will fit this, and I dont know what I need to get this to work.

Will I need to bring this to an exhaust shop and have something welded? or will a 2.5 adjustable test pipe work?

If anyone can help that would be great thanks

 

An adjustable will work for you as long as the flanges on the test pipe are the same as the flanges on your current exhaust.
