Subaru WRX Axle Back

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 WRX axle back exhaust setup on the 2.0L motor. The boxer exhaust from the factory totally hides the sound of the car. With the factory exhaust, you might as well be driving a vacuum cleaner. The first time we started up the WRX, we knew that we had to uncork the boxer exhaust.

cp-e® has developed Subaru WRX Axle Back for the 2.0L Turbo.

Designed using the latest in CCM and CAD technology, the cat back is a masterpiece. With that, we're proud to say that we've met our goal. This EcoBoost exhaust is characterized by an aggressive sound along with drone-free cruising.

This axle back exhaust will not only improve the breathing of your Subaru WRX, but it will also give you that aggressive exhaust notes 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. Even so, the exhaust has a pronounced and aggressive tone at wide open throttle. In summary, this is the ideal mix between raw tone and refinement.

Never overwhelming, the new cp-e® sound will grab attention. Although, 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 back pressure. One thing to keep in mind while shopping for an exhaust is that tone is equally important to volume. The perfect volume can be ruined if the tone isn't on point.

Subaru FA Exhaust - Getting the Most from Your WRX

For those who have replaced the factory downpipe, this 3″ axle back will remove the last bottleneck in the exhaust stream, increasing the engines breathing capacity and smoothing out the turbo spool. In addition to sounding good, you also want an exhaust that performs. With this in mind, we've developed an incredibly free-flowing system.

cp-e® uses Titan™ finish 304 Stainless Steel for all of our exhaust systems. We mandrel bend and cut the 18g heavy duty stainless piping on our in-house CNC Bender and CNC Mills. The system features custom cast Stainless Flanges, reliable hangers, custom made Stainless Mufflers and polished stainless tips. Everything is TIG welded by hand to get beautiful color and durability in the welds. Designed fully in a CAD environment, cp-e® is able to guarantee a factory-like fit every-time with great performance gains.

All cp-e® products feature a lifetime warranty.

The axle back comes complete with all necessary hardware required for a complete and professional installation.
