Curious what other exhaust mods you got? I've been reading a lot of old threads cause I'm getting ready to put in the MSDS headers. Is it possible you have lost too much back pressure? Theres a guy running the headers, high-flow Y, high-flow cat.....back to 4" supertrapps w/16 discs on each. He was running without the first cat and complained about lost low-end torque. He gained it back when getting the high-flow cat.
On another note, the shop where I had my Borla installed told a friend of mine that it is illegal for them to tinker with the OEM cat? Does anyone know what the hell this is all about before I go out and spend $80 on a high-flow cat?
