exhaust system

ZJ getting new Magnaflow high flow cat and muffler 2.5 inch tomorrow should sound way better than the rattle can and rusty muffler I have now. Also going to install new upstream O2 sen so I can pass smog.

Yep, I already have one.Will be ordering something to take its place very soon. Right now I'm looking at the APN. I have the OEM front pipe coming. Just kinda hung up on the cat and muffler. I am leaning towards the magnaflow15857 cat back. I've seen some post where high flow cats drive the rear 02 to throw codes. So I,m kinda hung at that point. Will probaly get the direct fit magnaflow cat and then the cat back. Will have to have the cat exit expanded or use a bushing of some sort to go from 2.24 to 2.5
