Some have the same size exhaust as the HD Vortec Gas trucks. Ive seen several, but I don't know why they would have a smaller exhaust. I just know some up here have smaller than 3.5"
Now that you mention that, I also have an 08 2500hd gasser and I believe it's a 4" exhaust... I could be wrong thoughI'm not trying to argue just curious as to why gm would put an exhaust from a gas truck on random duramaxs? Considering the front pipe from a gasser won't fit and a dmax front pipe is 3.5" so it would need a reducer after that pipe. Do the vortec hd trucks have a 3"?
