Gmmg
and as far as all they will need. made two or three years ago. but with todays market and **** out there to make big horse for cheap. you need good flowing headers. and ones that you wont repalce every two to three years
OP: I've had a GMMG for four years or so. I'm going to try a different set-up this spring. If I like it, my GMMG (rear section only) will be for sale for a reasonable price. PM me if interested and I'll keep you posted.
