On a stock motored LS1 F-body, the MAC catalytics will cost you about 5 rwhp on the dynojet. This might translate to about a half tenth in the 1/4 mile slower than with an offroad Y.
Sound wise, I think the cars sound better with cats in place, it is a more refined and deeper sound, without any metallic raspiness.

Agreed 100%. This is exactly what I’m doing, RT cats in a MAC ORY pipe.
