Ahh got ya. Hmm. Well let me think about it. I haven't had issues with my SW cats. Can't speak for ARH...what problems have you seen so i can look out for them. I usually keep stuff in case i need to sell or trade and go back to stock. will keep you posted.

i install them 2 years ago like every body else here recommended , but now after i have whipple sc and dyno tested and compare with same truck with stock headers we find out that they don't add a s@t , and both trucks have same 510-518 hp . but the big problem is the cats that on high rpm and hp give some restriction in flow and make you lose some power . this is apply to all non stock long headers . only short headers with stock cats can perform better .

This may be a stupid question but I assume I would get the same results even though I am N/A? Sorry to slim for going off topic, that was last question I promise

exactly i have them before the SC with 5 star tune and not noticeable change over stock with same tune . if you don't believe me go to JDM in NJ and they show you on dyno that there is no significant difference .

P.S
I'm just pist off that some vendors here sale you parts and promise a lot but don't have documents or test to prove there product .
