No disrespect, but I've heard of plenty of cats failing by several extremely reputable tuners here on C5. LT headers and Hi-flows just don't mix north of 600 RWHP IMO and researching. (even shortys with high flow cats have failed) I think a "perfect tune" that doesn't risk possible detonation or cat damage for the long haul at much higher RWHP is not obtainable. If emmision testing is a concern, the cats need to be installed for testing and keep a light throttle, then removed till next testing time. Every hi-flow cat manufacturer's excuse has been "poor tuning". Two high end cat manufacturers both reccomended this to me.
