I've been contemplating getting the RT cats for a while now. Lately I've been hearing too many problems that go along with them.
I figured for $180 you really can't go wrong the test pipes. I've seen some pics of the Helix welds and they look pretty sturdy. This will be my first time ever using any type of test pipe, I can't wait. Along with my Nismo exhaust, hopefully it will sound pretty decent
