Default Hi Flow Cat Converter Question

Hello all,

My 99 Vert has shorty headers, X-pipe and stock mufflers.
It has a good tone and is stealthy.
However, I wish to have the tone just a little better.

As a step before going to the Z06 muffers, what does the hi flow catalytic convertors due to tone? Anything?

Kenny, I would also be very interested in this question. I have a new exhaust and I was considering high flow cats to make the exhaust a little louder. Please let me know if you hear anything.

I have wondered the same thing. FLP makes a great combo but wondered about the cats. Does it add in performance or is it more for sound? :confused:

In a nearly unrelated thought - I was thinking about scarfing up some take-off Z06 hi-flow cats to put on my older truck. I can't think of a reason it wouldn't work, provided the inlet/outlet sizes are the same.

If you find some let me know as I have found that they are almost impossible to come by - unless you steal them.. :jester

I do not believe that Hi Flow Cats will make a performance difference. The stock cats are NOT a bottleneck. There are cars out there running over 500 HP w/ stock cats.

However, I would assume that there would be a more aggressive sound??? :confused:
