Dudes..what are the options available to us 4x4 guys with the 5.3's...I was planning on a Pacesetter long tube header but they don't do the 4x4's and the Thorley's seem to me like more of a mid-length header than a long tube...

Your right about the thorleys I have them. Others are stainless works and ASM both are expensive but they will work.

 

Damn....how do you like the Thorley's...a buddy of mine has the Supermaxx system but forget about paying $1,300 for headers/hi-flow cats/ etc...**** not for the Av.

Thorleys are great for the price you cant beat em, just wish they were longer. Fealt like I gained more off redoing the ypipe with no cats then the headers

 

Do you feel the Thorley's still provide more of a performance boost over a shorty Gibson even without the Y-pipe w/cats?

 

asms arent a bad choice, they fit perfect on my brothers awd SSS.

 

The coating on ASMs suck, after just a year of driving including one winter, the bottoms and collectors are all rusted and the coating is flaking off. I'll have to take them off and get them recoated at some point when the truck is no longer daily driven.

The gains were very nice and the install is not too bad if you have access to and know how to weld.
