Default High Flow Cats... Please Help

What are the best cats to buy for a c5 and where? Will I notice an increase over the stock cats?

I'm running stock manifolds, a Magnaflow X-PIPE, and B&B Bulletts on an 01 Coupe if that helps.

The buck seems to stop at Random Techs.. their a bit pricey and as an alternative the dynatech powercats have been mentioned as identical and less $$$'s.

Call West Coast Corvettes and ask for Paul, if you're also looking for an x-pipe.. mention the tpis xpipe and cat combo and you wont be sorry..

I don't think they will give you much power unless they are mated to some long tubes. My $0.02

They will change your exhaust note some, but I would not expect much HP gain on a stock engine.

TPIS Long tubes with Random Tech High flow cats and x-pipe with GHL exhaust.

all of these , long tubes, high flow cats. high flow x-pipe and good exhaust are needed for additional power. adding only one or two realy wont give much more HP.

Then better air intake and of course the dyno tune to make it all work together. piece meal dosnt do much

Good Luck
