I had Gibson headers & exhaust system on my 05 Ram & couldn't wait to get the money together to purchase this Gibson exhaust for my GMC Sierra! Please cut the old exhaust in half to remove easiest way. Install of Gibson was easy I did it myself on a lift. I did opt for the stainless steel version and it looks & sounds like grown man stuff! Just buy it the system you will not be disappointed. Auto Anything is AWESOME! Got it to me quick! Will be buying more items to complete my build up!

This system is of great quality. There is absolutely no drone which is awesome when pulling a load. I would recommend this exhaust to a friend

The quality of the exhaust system was excellent and the installation was easier then I expected. I was able to use the factory hangers and everything fit nicely. The sound was what Gibson said it would be a deeper throaty louder then stock . I'm very happy and would recommend Gibson exhaust systems to everybody looking for quality, installation, sound. Thanks Tony
