Okay just received my JBA headers yesterday, planning on doing the install this weekend but before i get started i thought i read something here on the forum stating that the stock cats should be replaced with high flow cats.
My question is are there any other members out here running JBA headers with stock cats and having no issues? I also have a AEM Brute Force intake and superchips Cortex. One other question i scrolled thru the Cortex and did not see A/F ratio options is this feature available with the Cortex or only the Flashpaq?
