Kooks are very expensive.
The top (2) go to's for Long Tube headers for our trucks is ARH (American Racing Headers) and SW (Stainless Works).
As far as a catback, the Attack will be very loud, almost all "catbacks" are designed for stock manifolds/cats. With headers and hi-flow cats it will be much louder.
Figure out exactly what level of sound you want from your truck and do 1 step down from there when doing headers.
I.E. Borla attack - go S-type with headers. S-type - go Touring with headers, etc...
Not to be that guy, but money is irrelevant when it comes to my truck. I want the best.. I can’t find one bad thing about kooks. ARH headers, I have here and there.
I don’t want this thing to be obnoxious loud at all. But a deep sound with no drone or rasp. Unicorn , I get it. But I want close as possible.
I’m currently waiting for a 2.5 thump cam from jay greene, and it’s getting hellcat lifters. I’ve read a few places the Borla “blew out” on some guys. Because I was really deciding on the atak series. Uggh, what to do…
Thank you so much for the reply.
