so I got this 4 into 2 into 1 header and downpipe but I need to attach a cat and cat back exhaust to it, the header ends at 3 inches and the downpipe reduces in size from their to 2 inches which seems kinda small but it's a 420a so whatever.
was the 420a cat diameter and cat back 2 inches.... I've got a leaking flexpipe so hoping this pipe can replace it and the manifold.
I'll find out by crawling under the car if I have too but just wondering if anyone knew offhand.
