so as we all know lots of companys dont show listings for our truck as far as mostly compatible stuff.
was looking to do headers and full exhaust on my 07. does anyone know if the y pipe is shared with a gm pickup?
was looking to do middie length cat forward headers and y pipe will do shortys as a last resort. not really looking to do full
length without finding a kit that will bolt up to a cat back exhaust. this kit from american racing headers looks real nice

called company the headers will of course fit but even they dont know if y pipe will just curious if anyone knows if we also share the y pipes with gm trucks

thanks

 

A few people here I think can answer that. I would say Yes.(BWTFDIK) why,,, Well the front end of our rigs are GM 2500 trucks guts. The frame is extended in the middle. It may fit with the crossover Y pipe. Maybe you could work out a deal with the vendor to return the assembly if it doesn't fit. And also maybe he could make alterations to make it fit which would open up the HUMMER H2 market.

Just my $.02 worth

 

yeah thanks even if they fit, the cat back part probably wouldnt because cat foward probably wont end where its supposed to.
i live in crappy ny. not really trying to bypass any emissions, even though my truck is emissions exempt (saftey only)
i am just starting to have some exhaust noise til gasket swells up. hopefully bolts arent broken yet, but probably will when I either try to tighten or loosen the bolts. figured if I have to remove manifolds I would replace with headers. shortys are useless for performance but look nicer , doubt they hurt, the cat foward I tagged are mid length headers, expensive with the cats though.
