I have Alphawerks headers ready to install, and I’m shopping for high-flow cats. This is my shopping list:

Ultimate Racing
$495

Crawford Z Car Service
$485

Kinetix Racing
$385

Helix
$440
no brace brackets

I’m on a budget, and would like to spend less that $400. Are there any high-flow cats from a reputable manufacture that I may be missing? Thanks.

 

You could save a few bucks on the Ultimate CATS at Z1 Performance.
$439 + $35S+H

Thanks but my budget is $400.

 

just get a SSV intake manifold

 

I did a search, and the only high-flow cats within my budget are from Kinetix Racing. I ordered a set today.

 

You will be happy with them... The welds on mine are extremely clean

 

Is there a difference in performance with these different companies?

 

I’m not certain, but Kinetix fits my budget. I’m looking forward to header and high-flow cats installed in the next moth. I figure that since I’m going to have the Z on the rack for the header install, that I may as well replace the OEM cats at the same time. I’ll be sure to post photos of the install.
