Anyone with GM Performance Cat-Back Exhaust/Air Intake ?

Recommended Posts

I was using the build and price option for the 2019 Silverado and there's a option there "Performance Upgrade Package" which adds 10hp for the GM performance exhaust and 5hp for the intake. I'm wondering if its worth the money?? or is it better to go buy aftermarket?

Also do anyone have it and what is the sound like?

I have both on my AT4 with the 6.2L.  I have had several compliments on how good the truck sounds.  Nice rumble on a cold start and loud enough for me when you step on the gas.  Quiets down nicely when you get up to speed on the highway though.

I'm anxious to hear how the factory upgrade is so I don't have to fight with a dealer over warranty if I buy an aftermarket exhaust.

 

I heard one at a dealer and it sounded great, but I couldn't hear what it sounded like on the highway because the truck because it was trapped 5 deep behind other trucks.

Any chance we could talk you in to posting a video of cold start and cruising? PLEASE!

There was a couple youtube videos of the media event for the Sierra.  Thsi one is an At4 6.2 with the GM performance exhaust It sounds about as loud as a Borla or Corsa touring exhaust.  My Corsa Sport on my 2014 6.2 is louder than this truck

I have a new 2018 Sierra Denali 6.2. I had the Borla kit put on by the dealership for $1,200. It sounds great.  I then added a K&N intake, it now sounds amazing.  Best part, very minimal noise at cruising speeds around town or on highway. It’s really nice.
