Al-Safadi custom headers from the engine fit on short beds from (2014 to 2019) And fits on Tahoe or Yukon from (2015 - to 2020) GM performance muffler (GM performance) The part cost 5000, selling the whole thing for 1000, non-negotiable, free of any cracks or welds, God willing. It was installed on a 2016 Yukon model. It fits any car but needs modification of the engine exhaust pipes. The rest will be adjusted by the exhaust shop. Riyadh Don't ask me what it fits ((The pipes can be shaped by the exhaust shop, the mounts can be moved, the exhaust fits the mentioned model, I have no knowledge of others)) (I have similar ones for models 2010 to 2014)
