Just bought a 2007 Avalanche and would like to put dual exhaust on it. Systems I found in the net shows taking off complete system. I am looking for a cat back system where I can leave existing tailpipe, add a muffler with 2 out connections and another tailpipe for the opposite side. I believe my system is SS already. Am I asking too much? Probably will have to go to a muffler shop. Not real reliable in my area. Any suggestions? Thanks, John

 

yeah youre asking too much. keep in mind anything custom will cost more, an exhaust shop should be able to get you setup right. if i was you i would just go with a cat back dual system and install myself. think that would be cheapest all around
