Crawford Z Car Does It Again!

These cats will fit any aftermarket exhaust that bolts up to the stock cats. There is no change in orientation or location of the flanges that secure to the cat back exhaust system. Crawford has only had one semi-local customer with a HR motor who donated his car for the fabrication of the jigs. He was very satisfied with the results, but decided not to dyno.
I drove the car before and after, and i could feel and hear the difference.
From what I have seen . . . these are the largest opening and cross sectional area after market cats for the HR. The difference in design from the non-HR cats allow for more straight through flow (i.e. you can see right down to the honey comb element as there is less bend). I wish i could get that flow on my car.

Why can't you provide some dyno numbers??? I'm not doubting Crawford in any kind of way, but I would hate to know that I spent that much money on something that gives very little gains

This should be expected since the cats are one of the most restrictive parts of the exhaust system.
