I have a 2001 camaro with a cam and long tube headers and ory with no cats and a loud mouth 2 and its really loud to the point im about to rip it off and sell it. my question is my car is tuned and the cats were deleted, to quiet down my exhaust could i put a high flow cat on? Will it make it quieter at least were I can drive again?

I had a loud mouth 1 on before this and one of my buddies said the loud mouth 2 would quiet it down enough but that didn't work!!!

 

Put your cats back on and throw on a corsa catback system thats what im running and its quiet till you hit about 4k rpm's

Note this video is without long tubes. And honestly its still pretty quiet considering this was WOT

 

High flow cats really quiet it down and kill the rasp
