Found a killer deal on some longtubes and ypipe local to me but they’re for a 15-20 GM truck anyone have any personal experience with that? Mines an 08 Escalade . Thanks guys

I know the '15+ trucks have an LT engine and our trucks have an LS engine so I am doubtful that they would fit but I haven't ever researched it either.

The flange bolt holes are a different pattern, for one. I don't know how the port spacing or surface angles compare, though.

i dont know, but i doubt it
however... you could swap in a Gen V l83 or l86... then they would fit
(*plus all theother work required, lol)
