I didn't notice much of a difference (dual catco 2.5") but another guy I talked to (Raymond) said his car got quite a bit louder.

Anybody else have any thoughts about the catco high flow cat???

 

Just put a Random Tech cat on my LB9 with stock exhaust, didn't recognize a difference.

 

When I installed my Catco 3" converter, the car got noticeably louder with a deeper tone. However, my old cat was so clogged it was probably only flowing 50% of what it should have been.
