Louder than I expected on the cold start minimal drone noise in the cab but definitely screams on a aggressive take off put it on a 2021 Chevy 5.3 trail boss self install was very easy took about 2hrs
I love the new sound of my Chevy, now it sounds like a pickup truck. Not sure my MPG will go up, it sounds to cool when I step on it
Sounds great! Seems loud at startup but quiets down and has a nice deep tone! No drone! I would definitely buy it again! Install was a breeze!

Q: Is this the best exhaust I can put on my 2020 Chevy Silverado trailboss Answer this question
A: This is an aftermarket cat-back exhaust system. Best is subjective. It will allow for more exhaust flow than stock, which does increase engine efficiency and increase available power. The main component to exhaust systems is the tone. Some people find quiet tone to be best. Some people like loud better. A video with sound will be available very soon showcasing the stock vs Borla exhaust notes.

BORLA Performance Industries started over 40 years ago, producing exhaust systems for ultra luxury and ultra performance vehicles including Rolls-Royce and Ferrari. From that history, BORLA developed and patented a host of manufacturing techniques that give their stainless steel exhausts the durability and performance that Jeep drivers flock to. BORLA even patented the way the steel is processed for their Cat-Back system, Header and Axle-Back systems. All use premium, high-quality austenitic T-304 stainless steel, which is better than 409 or aluminized steel. The construction of the exhaust systems is entirely welded and produced with mandrel-bent tubing. It's these high-end manufacturing techniques that make BORLA the go-to exhaust for off-road racers all over the world. Shop Borla Now
