Description

The SLP Loudmouth Axle Back Exhaust System is engineered to replace the restrictive stock exhaust on your 2015-2017 Mustang GT 5.0. This system features fully mandrel-bent 2.5-inch stainless steel tubing with minimal bends to reduce backpressure and allow your Coyote engine to perform at its best. Constructed from durable stainless steel, this axle-back system includes two 4-inch polished 304 stainless steel tips with an engraved SLP logo, providing an aggressive look that complements the Mustang's rear fascia. This Loudmouth LM-1 system offers a significant weight savings of 29 lbs. compared to the stock exhaust. It is also 50-state emissions legal. However, as a straight-through system, it contains no sound-deadening material or resonators, and users should check local noise ordinance laws for legality. The system is covered by SLP's performance guarantee and a Limited Lifetime Warranty.
