cp-e™ Austenite™ Ford Mustang EcoBoost Axle Back Exhaust System



OEM parts often times are designed for efficiency of manufacturing, cutting costs and driver comfort. Unfortunately performance is often not a priority – as seen on the very restrictive factory axle back setup on the 2.3L EcoBoost motor. cp-e has developed a high-performance Mustang EcoBoost Axle Back.

Designed using the latest in CCM and CAD technology the axle back is a masterpiece. Lastly, the end goal of aggressive sound along with drone-free cruising has been achieved.

This axle back exhaust will not only improve the breathing of your Mustang EcoBoost, but it will also give you that aggressive exhaust note you’ve been looking for! The cp-e™ Austenite™ axle back exhaust has a very controlled exhaust note that gives the driver no drone at cruising speeds, yet a pronounced and aggressive tone at wide open throttle.

Never overwhelming, the new cp-e™ sound will grab attention; not from obnoxious noise, but because the sound is exotic and unique. These pipes keep the exhaust at a nice tone while also eliminating drone without adding backpressure.

Mustang EcoBoost Axle Back Construction

For those who have replaced the factory downpipe and mid exhaust, this 3″ axle back will remove the last bottleneck in the exhaust stream. Increasing the engines breathing capacity and smoothing out the turbo spool.

Plus Titan™ finished 304 Stainless Steel is used for all of our exhausts. Additionally, we bend and cut the 18g heavy duty stainless piping on our in-house CNC Bender and CNC Mills. Thankfully the system features custom cast Stainless Flanges, reliable hangers, custom made Stainless Mufflers and polished stainless tips. Not to mention weTIG weld by hand to get beautiful color and durability in the welds. We design fully in a CAD environment, and we’re able to guarantee a factory-like fit every-time. Combine this with great performance gains and you have the best EcoBoost exhaust on the market.
