Don't think that's true. They didn't do it on mine. They just put the GFX on and didn't touch the stock exhaust.
When I had the GMPP axle-back put on they just cut the pipe ahead of the stock muffler at the spot indicated by GM and slipped the GMPP pipe and muffler on. There was some back and forth the get the pipe the same depth in the GFX stainless bezel. Got the GMPP with no tips cuz the 4.25" round GMPP tips won't fit in the GFX bezel. I had some generic oval tips put on, and that's where the time was spent getting the tips aligned with the GFX. Had I done the exhaust + tips first there's no telling how the tips would have lined up. I'll be doing a Magnaflow 16483 3" cat-back soon, but with MBRP rectangular tips. The GFX of course will already be on, but I don't see how anyone can get tips "right" by blind guessing with the GFX not already installed.
