Review on 🔊 Borla 400286 ProXS Metallic Muffler - High Performance Exhaust Upgrade (4 inch) by Bob Candfield

I have to say right away that I'm a Borla fan now. I've always been a fan of the Flowmaster since I built my first exhaust. I recently installed a Flowmaster catback system on my 2014 Tundra and loved the sound, but the drone killed me with its 5.7 liter engine and long nozzles. Install this Borla silencer to tame the drone and calm it down a bit and that's exactly what I got. I like how it sounds and without drones. But the roar is audible in the cockpit. People might say you have a custom exhaust, but that's okay. Don't get me wrong, Flowmaster is a great company, but this time Borla won.
