I am looking at headers for my truck. I need to keep cats so my options are
limited to ones that have a catted y-pipe. So far I've looked at Kooks, ARH, and Stainless Works. Does anybody have experience with the catted ones?
Any one use better cats or has a better setup?

 

Use the search button there's a new thread a day on longtubes. Theres plenty of info around about them.

Just depends on how much you want to spend etc

 

I know theres a lot of info on here, but everybody seems to be running an ORY.
I am inquiring about the setup for cats. I like the ARH and stainless works. I know what they cost. I just need to know how they perform with cats.

 

Cats now-a-days don't have near the restriction that they used to. I don't think you're risking of losing much of anything honestly.

I think that TSP has pacesetters with the catted Y

 

The ARH with cats are very good quality. I've installed several of them, and never had any issues at all.

 

Most of the aftermarket header systems have high flow converters..

 

I have the ARH system. The cats are good. I don't mind paying for system, I'm not going to sit here and complain about it.

 

go ARH , best quality , CS,and fit&finish and last but not least performance

 

ARH headers w/ cats vs w/o cats is 12hp on a 620hp LS3. Less with less power. Also quieter. How much, I have no clue as nobody has a db meter...

Do your eyes and lungs a favor. Cat it.

 

Agreed, the use of high flow cats these days doesn't loose any power.

We do have a sale on headers till the end of December
