Replacing cats with high flow...power/sound gain?
Wanted to see what you guys thought about high flow cats. What do you think my gain in power and sound would be if I replaced my cats on my 2002 Z06. I cant get them very cheap and wanted to see if there is any pros or cons.
Thanks
John

For a stock car I think any gains in power would be marginal at best. The sound might change some, engine noises will sound a little sharper. Bottom line any changes would be marginal at best and aftermarket cats usually are not as good as stock, won't last as long.
