Nameless Axleback Exhaust - Quad Exit Dual Chamber - 2024+ Impreza RS 2.5L

The wait is over—our dual chamber no drone exhaust system is available now, tuned specifically for the FB20 engine in the 2024+ Subaru Impreza Base or Sport Model. And what's more, it's now available in our single exit series, featuring a 3" Double Wall dual tip, and an upgraded mounting solution including a three hole urethane exhaust hanger bushing.

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 2024+ Impreza Wagon with OEM or OEM fitment midpipe. 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 axleback exhaust system comes with a full hardware kit, gasket, and three hole bushing for a simple and clean installation.
