Has anybody had any problems with emissions while running a magnaflow cat on their s13 KADE?? I’ve done a tune up, and am planning headers, and I figured just swap out the cat for a high flow one. Hows the gains with a 2 1/2" cat back aswell?? Thanks guys!
The only thing you’ll be gaining is noise.
I passed emmisions on my SR with a 3" magnaflow, so it should not have any emmisions problems.
