i almost bought the exhaust from GRD but after i spoke to tuan about the exhaust, he said it was nice but not worth it.

second....dont always rely on the dealers to fix problems, it doesnt work that way, find an installer you trust and build a friendship with, that counts more than anything.

i didnt have any problems with faulty wiring harnesses. i just had the check valve problem which was an easy fix.

How bad would be to run it with stock one?
