Nameless Performance Dual Chamber Axle Back Exhaust 2018-2021 Crosstrek / 2017-2021 Impreza Hatchback

The wait is over - our dual chamber, single exit exhaust system is available now, tuned specifically for the FB20 engine in the 2018+ Subaru Crosstrek and 2017+ Subaru Impreza Wagon.

Ever wish you could have an exhaust that was quiet when you want quiet yet aggressive when you want aggressive? Wish no more! our new Dual Chamber exhaust system is here!

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".

Featuring both a 5" conventional "zero-restriction muffler" and a frequency tuned "helmholtz" resonator. Want to know more about the science behind this design?

"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 2018-2022 Crosstrek or 2017-2022 Impreza Wagon with OEM or OEM fitment mid pipe. Specifically for the FB20 Engine only! Will not fit the older models! This will not work on the Crosstrek Sport model with the FB25 Engine. Looking for a unit that will work with that engine size, check out our Dual Chamber for the 2.5 liter.

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