First of all, would putting a hi flow cat on a car with no other exahust upgrades do anything? even 1hp? better sound?
Is there one that has been proven to show the best numbers already?
I found these on eBay and wondered wich would have the best features for the money, and if all of them would fit with a OEM system for now and aftermarket in the future.
(I know some of these are ended, but they should still be around)
