Well I didn"t want to spend $3K in the exhaust on a mostly stock truck like mine so I decided to give porting the manifolds a shot since I have read about others doing it. I recently also had the cats deleted at a local muffler shop, had #12568 Magnaflow installed and made my own mechanical O2 simulators. I'm probably going to make some custom stainless tips too.
