Axleback Exhaust - 2024+ Impreza - Quad Exit 2.0L Dual Chamber - Neochrome Tip

For years we have had requests to develop a quad exit exhaust featuring our drone cancelling Helmholtz resonator.  The wait is over with these new quad exit exhausts for the 2024 Impreza Base & Sport.  Tuned specifically for the FB20 engine to cancel drone at cruise and high load / low rpm driving, this system is the best of both worlds.

This version features blue neochrome (titanium oxide plated) 3” staggered double wall quad exhaust tips, tucked perfectly into the bumper features on the 2024+ Impreza.  

So what is our dual chamber exhaust all about?  

Ever wish you could have an exhaust that was quiet when you want quiet, yet aggressive when you want aggressive? Wish no more! 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 inside the car, and an appropriate growl inside and outside when you feel like doing some "spirited driving". 

Featuring both a 5" conventional "zero-restriction muffler" and a frequency tuned “Helmholtz" resonator, this gives a warm exhaust note outside the car while cancelling the specific drone frequencies that occur at cruise and low rpm load (hill climbing, etc).

 "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 Base or Sport (or any other 2.0L model variant) 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 and new gasket.
