Good choice on the CSP headers and Gen II cats. That’s what I have. Fit was excellent. I went that route a year ago because I wanted CATs and figured I’d be going FI soon. Have a 2650 I’m working on installing now, so I hope they live up to the hype.
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.
