Well I only went from the cat back it's all svt stock,but it must be a lot less restrictive because there was a noticeable loss in back pressure It's res less.I disconnected the battery and no improvement so I am not sure what to do to fix this I might try putting on a Edelbrock res: from summit!!
As far as the cat is concerned I'm not sure about that sorry
Well got to go for now

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?
