Overview

The MRT Street Race Catted H-Pipe is a performance exhaust component designed for the 2011-2014 Mustang GT with the Coyote engine. It features 3" mandrel-bent T304 stainless steel tubing and 200-cell race catalysts to maximize exhaust flow, reduce back pressure, and improve horsepower and fuel efficiency.

This H-pipe is engineered to enhance the deep muscle car sound characteristic of the 1960s, providing an aggressive tone with noticeable but tolerable drone. It replaces the stock exhaust from the manifold flange to the cat-back attachment point, offering a do-it-yourself installation for drivers seeking more performance and sound.
Show original supplier description
The MRT Street Race Catted H-Pipe is a high-performance exhaust modification specifically engineered for the 2011-2014 Mustang GT equipped with the 5.0L Coyote engine. Crafted from durable T304 stainless steel, this H-pipe features 3" mandrel-bent tubing and incorporates 200-cell count race catalysts. This H-pipe aims to deliver an enhanced exhaust note, described as a deep, aggressive American muscle car sound reminiscent of the 1960s. While it provides an aggressive tone at wide-open throttle with a lively attitude and deeper growl, the manufacturer notes minimal drone and that any resonance is generally considered tolerable. It replaces the stock exhaust system from the manifold flange to the cat-back connection point, offering a direct fit and an out-of-this-world driving experience. **Important Considerations:** This MRT Street Race Catted H-Pipe is intended for **closed course competition use only** and is not legal for use on street vehicles. Its sale, use, or installation may be illegal nationwide under the Federal Clean Air Act. Purchasers are required to sign a Vehicle Compliance Waiver. Additionally, installation may require a tune, and is estimated to take 2 to 3 hours. Customers in the Plymouth, MI area can contact MRT for installation appointments.
