HP gains from 6.0 Vortec
A stock muffler is quiet and restrictive for horsepower gains, especially if you have installed a new cam and/or turbo in your Silverado or Sierra truck.
A good sounding muffler and headers can be less restrictive. The pipes allow that large V8 to breath and give the most HP from that Vortec.
My experience: Flowmaster on my Silverado
The Flowmaster sound is synonymous with muscle cars and muscle trucks. Their chambered mufflers sound good, and I like that they have cat-back kits.
The full exhaust kit makes it easy to upgrade. Also, it’s easy to pick the right tone with their muffler sound comparison video.
I used a Flowmaster 40 series on my Silverado. The muffler had a nice low grumble at idle.
The full exhaust sounded good when accelerating and did not drone when going 55 miles per hour.
