So I am shopping for long tubes for my 04 gt road course only car. I don't know if I need the 3 in or 2.5 or size of primaries. Or if mid lengths are on option. Money is a non issue but who doesn't want to save a little scratch. Currently the car is supercharged but with eventually have a fully built n/a teksid block and a more superchared friendly teksid block. One for high altitude and one for sea level. Car also has a magnum t56 so hope they will clear for clutch changes. Will be doing the same time as k member and coil over setup. Both will have port matched trickflow 195 cylinder heads. Not swapping to coyote or 4 valve, yet. Just need opinions on Long Tube Headers. Looking from anywhere from 450 engine hp to 550. Thanks guys. Started a build thread in road racing section.
