Need suggestions for High Flow CATs
I'm looking to add hi-flow cats back on my car with aftermarket catback.
Can someone suggest ones that they have used and will fit a C5.
Part numbers would be ****

More questions than answers.
-Do you have headers or stock manifolds
-Cats were replaced with straight pipes in factory mid section?
-Wanting a full mid section or just cats?
When I installed my headers I used MagnaFlow cats and X. But no idea what to suggest without knowing what your setup is.

STOCK Exhaust System OR aftermarket system???????????????????
I used Random Technologies High Flow Cats on my Stainless Works 3" system and they work OUTSTANDING!
This is a STOCK EXHAUST with PUP Cats off of a 2004 LS1.

sorry I should have mentioned it, I have TSP LT headers and x-pipe setup. I loved the sound and little bit of oomph i got from them but as I get older I can't deal with the smell anymore.
Random Tech, i'll look into them. Thanks.

Or maybe not... they no longer make cats.

If you're not concerned about price then get the Random Tech cats, they are prob the best high flow cats you can get. I did not want to pay that much so I bought some high flow cats by Magnaflow off ebay. They are a 200 cell count metallic core, so they flow very well. Also they do a great job with getting rid of the stink. My car made great power on the dyno with them. If u are interested I can find the part num.
