does mugen even make a twinloop for the 5g hatches? or do i have to get a itr or si axel back and custom weld on to my piping? i really wanna ditch my current setup for a twinloop. i just love the sound the stealthy look. i also believe the twinloop pipe on the itr is bigger then the si correct? and if anyone knows where i can pick one up that would be even more helpful. thanks
