GM Performance Exhaust

[Steven Tran]

Does anyone know what the entire GM Performance Exhaust consist of like where does it start. I plan on replacing it since it’s not loud enough.

Just like my Corsa, it starts on the down pipe from catalytic converter. Replaces stock muffler and exhaust back to the rear bumper if it has tips, if not, it replaces exhaust to the passenger rear tire. 

 

Get the full catback from either GM, Borla, or Corsa.   Do it right and you won't have any drone or other annoying noises coming from the truck with DFM.

I would love to know what this one sounds like. Anybody have videos, opinions, or experience with this?

You can go to youtube and search for GM Performance Exhaust.  There are plenty of videos out there.

Check this youtube video.  This is for the Chevy performance exhaust on a 2019 Silverado.  The part number is 84173601, which was replaced by 84964738.  This kit has the Chevy logo on the exhaust kit.  The GMC version of the same kit is 84173608 which was replaced by 84964742.  Same exhaust, just different exhaust tips.
