2008 vs 2012 Exhaust Fit

[JKeithley]

I have Dynatech Supermaxx long tube headers with the y-pipe with cats for the 07-10 GMC 2500HD. I have ordered a 2012 GMC 2500HD with the 6.0 and not sure if the headers and y-pipe will fit on the new truck. Called dynatech today and they could not tell me if the system will fit, they are behind on their updates for the products they already have.

 

Not sure with the frame chance in 11 changed the exhaust routing, or if the exhaust system has changed in the 11 and 12's.

I can tell you this, my new 2012 6.0L 3500HD 4X4 has a different exhaust system than my company truck, which is a 2011 6.0L 2500HD. I don't know if the changes are due to one truck being a 1 ton 4X4 and the other a 3/4 ton 4X2, or due to model year.

Well, the manifold part numbers match from 2007-2012. The y pipe part numbers are different. 2010 they switched to 1 y-pipe that was 100% compliant with all emissions (cali, fed, etc) but it is a different part # than the 2011-2012 one, so they may be different, but they may be the same. 50/50 shot that would probably have to be test fitted.
