2014 Silverado muffler delete
5.3L engine. Just had the shop remove the muffler and install a piece of straight pipe. Cheap option. Doesn't have a drone inside cab and can barely here it when cruising but sounds great wide open.
Borla GMPP Touring Muffler for 2007.5 - 2013 Sierra / Silverado
Installed a Borla GMPP Performance stainless muffler for a GMC Sierra and this is a little sound byte to hear what you'd be getting if you were to order one. I had the catback system on my 2007 and loved it. In the new Sierra, just ordered a muffler to install. It seems that the tone is a bit deeper and a bit smoother than a Dyno max or Magna Flo muffler system. GM used to include these performance Exhausts in their accessories division and have since stopped offering them as well as other great performance parts. It's a shame as these are great upgrades to the Sierra/Silverado truck line-up.
2005 Silverado 6.0L No muffler or cats
This is a 2005 Chevy Silverado 1500 HD with a 6 liter. I was in the process of switching the muffler. We drove it in town after we cut off the old muffler. It was annoyingly obnoxious so if you like the sound, keep in mind the camera doesn't do it justice for how loud it is... You're definitely going to want another muffler. Truck also has no Cats. Shortly after this video I installed a Magnaflow 12268 Muffler which sounds alot better. about 45 seconds into it is when I step on it.
