If you dont already know, I work for Magnaflow Exhaust in Engineering and I have been procuring cars/truck for protoyping new systems and other components. Currently am working to develop and fit a system for 02'-03' 6.0l Denalis. Should anyone be in the Southern California area, can stand to drive a rental for a few days and get a free cat-back when we are done .. please let me know, or let me know if you have any questions.

I have an unrelated question for you. I have a Magnaflow 1 in 2 out 22" muffler on my 02' Yukon. I think it's part #12588. I love the sound but I've been wanting to go a little louder. Should I go with an 18" muffler? Round body style? 2 in 2 out? Thanks in advanced

 

Damn, I'd do it, but I don't have a Yukon.
How about an '01 shortcab short bed Sierra?
