i have an 04 gt. automatic. i wanna get some long tube headers. how much of a problem will this be?
also do i go with mid h or x pipe. which will sound better. i have the flowmaster force 2 exhaust not as loud as
the american thunder.

 

i think the bbk will fit a auto.

 

I know for sure SLP and MAC have headers that fit for autos, but I am not sure if any other brand out there fits.
