Just found this site. The have the banks stainless exhaust for the 6.0
Any one have this on their 6.0 yet?

 

I had that system, (Monster Banks) installed with downpipe a few thousand miles ago. I am happy with it although i do recommend having the installer (you or a shop) to weld the pieces together for better durability. Then tackweld the tip so thieves can't snag that either.
Thats what i did anyway.
The shop i deal with (Gerharts) is a pretty big national chain. The guys sell and install most brands and do in shop dyno tuning.
The Magna Flow brand appears to garner the most power at the rear wheels.
The Banks is pretty close and i saved $$.

If are going to the trouble of putting a system on the i do vote for installing the downpipe as well no matter what system you choose.

 

I have the Banks cat-back system. Sounds good. Fairly easy install.
