HKS axel back is what I'm running. I'll try to find the clip I have. I also have a stock muffler if you want it lolLooks like I got a good 2 years out of my $130 OBX exhaust before it started cracking up and getting all rusted up. Pretty set on a full racingbeat exhaust set up, paired with the corksport exhaust hangers.. seems to be about $500+$400 shipping to Hawaii. Anybody happen to know other places selling it? Or any other suggestions on an exhaust set up?
