I'm looking at getting a cobb cat-back to replace the loud exhaust (unknown make) that was on the evo when i bought it. With the cat-back it I'm looking for a Hi Flow Cat. Do you guys have any recommendations?
Is this a case where you get what you pay for? or one HFC is as good as the next?

Thanks!

 

If your going to use a cat just get the 100 CEL cat that mil.spec sells. It flows the most and will give you the best gains in the dyno testing done.

 

they only sell the cat as a weld-in unit though, so make sure to buy a test pipe with your new exhaust. youll have to weld the cat into the test pipe

 

That is definitely incorrect unless they changed their policy. I got mine from them with flanges and everything.

I see last time they did a sale they included the flanges as well.

I suppose you could pm Aby with a special request and see if he will build one.
