MRT Part# 90R232 Loudness: 6 Drone: 1 Performance: 8

For the Ford Bronco owner who wants to customize their full-size SUV to get a more sporty, performance sound, MRT designed the Trail Rated axle-back system with a simple turn down exhaust tip. This axle-back is a straight through muffler design, that tones down the exhaust presence giving it a clean exhaust note that's not overpowering. The turn-down tip is crafted of T304 Stainless steel and to keep the exhaust package out of the way so the Bronco customer's adventure is not compromised.

This MRT axle-back exhaust with turn down tips is handcrafted in the highest quality, premium, corrosion resistant, 2.5" T304 Stainless Steel and 100% made in the USA. MRT used a straight through design in the exhaust path for maximum performance - fuel economy, performance sound and most importantly FUN with this system. This axle-back lets the 2.3L EcoBoost engine breathe easily for performance and a good sport sound.

At idle, there's an exhaust presence that's not too loud or too soft; just a simple, nice soft whir in the background that is not overpowering. MRT engineered the system for a no drone presence and a driving experience that is not harsh or inappropriate. As you hear the engine go through the RPMs, you get a nice performance sound that is definitely sporty but subdued and in the background. With this trail-rated axle-back, you can hear some of the turbo whoosh and a little bit of whistle of the EcoBoost engine. This system is not obnoxious and not over-bearing. If want this sound in single polished tip option, check out MRT Part # 90R236.
