Question Regarding Helix test pipe
I just wanna know hows the quality of the Helix test pipe. i had Ultimate racing test pipe on the car for couple months, and its rusted pretty bad so i need a replacement pretty bad.
from the looks of it, it looks to be good quality and at gruppe-s.com they have the helix mechanical 02sim so that is really handy to even though it is not as cheap as making one yourself.
