MRT Version 2 Axle Back Exhaust (91U821) - 2016-2023 Camaro 2.0L Turbo I4
Upgrade your 2016-2023 Camaro 2.0L Turbo with the MRT Version 2 Axle Back Exhaust and bring out a deeper, more aggressive tone from your turbocharged platform. Designed for drivers who want a noticeable improvement in sound without going overboard, this system delivers a balanced, sporty exhaust note that enhances your Camaro’s personality both on the street and under acceleration.
Constructed from premium T304 stainless steel, this axle-back system features 2.5 inch mandrel-bent tubing and a straight-through muffler design to improve exhaust flow and reduce restriction. The result is better performance, increased efficiency, and a more responsive feel from the LTG 2.0L turbo engine. Dual 4 inch double-wall stainless steel tips provide a clean, aggressive appearance, with an optional black matte finish available for a more customized look. Built to match the Camaro’s performance DNA, this system delivers a refined tone with an elevated presence and controlled drone levels.
Positioned as the most balanced option in the MRT lineup for the Camaro I4, the Version 2 system offers a smoother, more controlled sound compared to the more aggressive variants. Engineered and manufactured in the USA, this system installs easily with a direct bolt-on design and requires no tuning, making it a simple yet effective performance upgrade.
