Dope. If check engine lights aren’t your fav n u wanna stay legal but still catch some gains n open it up without a tune. Berk HFC.. nice added note. Noticed a difference paired with an axle back.

I definitely recommend these over Kinetix products. The welds and craftsmanship are of obviously high quality and even has extended o2 bungs (unlike Kinetix). Also, all exhaust gaskets and hardware come for installing to the stock exhaust system and exhaust manifold, which was a major plus for me.

Bought these because oem cat went bad. Dealer wanted 800 for 1. Got these and so glad I did. Not only did the check engine light not come back,you feel a performance and sound difference. ABSOLUTELY RECOMMEND
