Im in the market for a 2015+ 2500HD with the 6.0. Ive seen a fair selection of exhaust systems for the 5.3 but not so much for the 6.0 as far as packages go. I know the new trucks have the same engine and transmission as the 07-13 2500HD gas trucks but im not sure if there are any differences that demand different exhaust routing or demensions. I'll be looking into long tube headers and preferably an X-pipe with true duels. Cats or no cats, i havnt decided yet.

Ideally, i wish someone offered a full kit from headers back. What are the options for the 2015+ HD gasser and who are the manufacturers to look at? Im looking for as close to a full true duel exhaust system kit as possible. Im not opposed to a single outlet if the performance is similar but i just like the duels. If there's none available i guess I'll just have to get the headers, X-pipe, mufflers and find an exhaust shop that will build it. So what are the options for this application?

 

I don't know of any brand mainly because I own a half ton and haven't looked into it but there won't be any power gains if you did dual or a single exit. The factory 3in exhaust is more than enough for fairly modded engines.

 

Yeah, seems like ive heard that before about the factory 3/4 ton exhaust. Maybe headers to a Y then a good single inlet duel outlet muffler will do. Either way, i cant find out for sure if stuff for the 07-14 HDs will bolt up or not. I know the headers should but im mainly talking about the Y pipe and intermediate stuff.

 

Look into kits for the 11-14 trucks especially.... chassis never changed even if the sheetmetal did in 2015. Probably the same setup since the GMT900 in 2007.
