This system offers the same crisp exhaust notes that our 5" muffled systems on the outside of the vehicle, while reducing cabin noise in the low RPM ranges. literally the best of both worlds - ultra mild at cruise, and an appropriate growl inside and outside when you feel like doing some "spirited driving".

 "New helmholtz exhaust designed by @namelessperformance received and installed. Impressive build, quality, and sound... and most importantly for my wife, absolutely no drone in the cabin. Nameless hit a home run with this one. Thank you!" was what our first customer had to say about this after driving the 5" muffler and wanting to have less cabin noise.  

Featuring factory fit laser cut flanges and 2.25" piping that provides excellent breathing characteristics for high end horsepower and torque while retaining the appropriate frequency to reduce in-cabin drone and keeping excellent sound outside the car.

Fits 2024+ Impreza Wagon with OEM or OEM fitment mid pipe. Will not fit the older models.  Will not work properly with 2.5L models.  We have a specific design that targets the drone frequency from those engines that is available separately from this system that is designed for the 2.0L. 

Each axle back exhaust system comes with a full hardware kit, gasket, and thre hole bushing for a simple and clean installation.

Recommended Add-Ons:

Exhaust Hanger Bushings

Upgrading to our long lasting Nameless Performance urethane exhaust bushings from the factory rubber bushings is highly recommended. The softer rubber factory bushings have too much flex and if you race your car or enjoy spirited driving the exhaust "wags" left to right which sometimes causes noise or the tips to touch the rear bumper on Crosstrek and Impreza applications. When this happens there is a chance your bumper can be damage or if you have a hitch or any other accessories can cause annoying sounds. The best way to avoid this is to use our urethane exhaust bushings to hold the exhaust in place. These upgraded bushings are not necessary to install our exhaust systems but for the small cost of upgraded units, it is an excellent idea! prevents common exhaust sag issues.

• 2 Bushings: Replace 2 rubber bushings on the axleback portion of the exhaust (third bushing is replaced with our three hole bushing, included with the single exit axleback exhaust).
