A few notes, use the GM exhaust bolts not the supplied hardware. In fact that was my only negative on the system. The hardware was kind of an afterthought. I just dropped the exhaust to put in a ZL1 fuel pump and all four supplied collector bolts twisted off. I’ll be going back with better bolts when I put it back together. But outside of that they are awesome. |
I’m pushing 850 through mine. Still ok almost a year later. Gen 1 not so much. I’ve got a box of blown out cats….. 3 sets total I went through.
