    LT header performance help

    I have a 2002 WS-6 M6. Last year I installed SLP LT headers and loud mouth with cats removed. I love the sound and have gotten lots of compliments but I am not really happy with the performance. When I am stopped and floor it, it kind of bogs down and seems to have no torque what so ever. The car actually has a problem even laying down a strip of rubber. When I am on a roll the car responds a little better but not like I would expect. The car has extremely low miles (6k) and I never really tested it before the mods. Maybe I just don't know any better and maybe my exhaust system is overkill with what I am running but I would expect this car to lay down rubber all day long. Other mods include MTI air lid, STB, and SLP SFC's. I would like to see a dyno tuner but don't know of any close to where I live in upstate NY near the VT and Canadian border. Can somebody please tell me what is wrong or give me some advice?

    baseballss is 100% correct, you really need a tune for your Bird. It will make a world of difference in performance and even your gas mileage.
