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.

 

Okay guys. List price on the cats are $535. The GB price will be $490 + shipping and there has to be a minimum of 10 people in this GB. Let's get the official list started.

Can you match Berks price of 449.00?? plus shipping (debating over Berk or Crawford)

Also what about dynos... or actual evidence of performance gains?

 

Sorry, no.

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

 

You have to remember Andy is just selling parts. He had nothing to do with the design of these HFCs. As stated the expected HP gain should be between 8-10HP and if you look at other HFCs you'll notice about the same. This should be expected since the cats are one of the most restrictive parts of the exhaust system.

 

Bump for GB!

 

You say that as if I don't want to provide dyno numbers. If dyno numbers were available, there would be no reason why I would not provide them .

 

Thank you. BTW, it looks like you have a Base model, want to buy a factory VLSD?

 

^^have a factory VLSD? how much?

 

Damn!!!! Why does this happen right when I spend money. If it wasn't for the project mu, I would be all over the list

 

hmmm. Very interested in these.

 

Anytime Andy. I'd be interested in the VLSD except I'm saving up for a Quaife. Never got to say hi to you at Ben's party. You left just after I showed up. I had that 66 mustang.

 

Monday lunchtime bump.
