I recently purchased a 2003 Cadillac Escalade with the Performance MagnaFlow Exhaust already installed, I would prefer to have the factory exhaust because it is extremely quiet. There is absolutely nothing wrong with this exhaust it's actually pretty expensive. I am willing to have this exhaust removed and will trade for a factory exhaust system. If there are any questions or concerns give me a call at 843-687-2932 or email me at Saleensstang302@aol.com Thanks, Bennett
