Borla names the fame in terms of quality and durable exhaust build. Most of the Borla exhaust is made and welded from the premium T-304 stainless steel, making them durable and rust-free for an extended period.

Contrarily, the Flowmaster exhaust system and muffler are made from mild steel to Aluminized steel. That is too sturdy enough. Some of the Flowmaster also comes with 400- series stainless steel made.

However, if you made up your mind with the Flowmaster and looking for the best Flowmaster muffler for 5.3L Silverado 1500 2019-1021 year model, the new FlowFX dual-mode muffler with 409 stainless steel is an excellent way to go with.

Wow, it’s the perfect sound! I find that I don’t listen to the stereo much anymore because this muffler sounds so amazing especially on light throttle cruising or when towing and hauling. The interior resonance is noticeable, but my wife and kids haven’t even complained. The exterior sound is not too loud either. It has the perfect bass tones and Flowmaster sound we all love. Everyone who hears the truck loves it.

Borla’s ATAK (Acoustically-Tuned Applied Kinetics) offers some custom-tuned exhaust sounds where the mufflers are solid-made with multicore tube shaping, and some innovative graphic precision equalizes the tone.
