BUT, many states and provinces don't require emissions tests.
I got mine for next to nothing, just for the hell of it really but it is for track only anyway and won't be an issue since very soon the car will be trailered.
And I already have a good high flow cat, so I guess I'll tell You how it feels and compares on a dyno next to my Carsound 2 1/2" cat.
BTW the Fereral Gov. also restricts the replacement of a stock cat with an aftermarket type and HF to any car over 50,000 miles or not able to function properly and meet requirements.
It's all relative.
