I am starting and putting in my own true dual exhaust on my 2003 Silverado 2500HD. as far as all the materials go I know what I am getting and know what I need.

Anybody have any suggestions on how to run it underneath?

 

i plan on getting from Pypes a crossover and cutting in front just past the 2 catalytics and custom bending dual exhaust through to the back . this should work with my 2007 6.0 but i am going to keep the original exhaust if i ever get pulled over by the highways officer i can reinstall it.i find that the complete exhaust with headers are i little pricy
