cat back means the whole of the exaust from the catalyc converter to the barrel of the muffler itself
-full exhaust is from the turbo or dump pipe
high flow cat is usually bigger than normal cats
try to get someone to make a custom exhaust that sits higher up,because your car's low and keep it that way heheh
ive seen another R34 GTT, but white,had a full kit, dumped to the ground, 19" what looked to be lowenharts and a chopped nismo huge spoiler-without the blade so looks a bit devilish with the two horns sticking out
hm i think i feel like modifying my front bar, getting decent side skirts and rear bumper soon,., my car looks a bit half -done, might put a GTR spoiler too(im not copying you!,i just got lots of holes)
the guys at Spoiler Shop are allright
