I'm not buying new headers but I might just buy the cats and have them welded in to my Kooks connection pipes if they'll fit which they should since the Kooks green cats are probably the same inlet size but 4" outer diameter instead of the 4.5" outer diameter that you have.

Yeah i think the 4" would of been unnecessary extra work to reduce it back to 3". Its 3" in/out with a 4.5" body. Looks like they changed the inside guts, and its also spun differently. I really do hope they hold up because i've spent alot of time/money on these stupid things.


I don't need to pull them apart, i just unscrew the front o2 sensor and run my endoscope camera down it. Takes a few minutes, much easier on my back in the garage then pulling it all apart


I think if your making 650-700 max I think the original Gen 1's might be safe BUT and this is a BUT the tune would need to be perfect and boost cant be crazy high or they'll def not last.


CSP did a very good job however, nice clean install, headers are very nice and the connections they had custom made are very clean as well. Just needed to weld it to my S pipes.
