Sometimes you want to drive around unnoticed, sometimes you want to want to have aggressive sound now with our new Dual Chamber Exhaust systems you can have both!

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 serious "spirited driving". 

Featuring both a 5" conventional "zero-restriction muffler" and a frequency tuned "helmholtz" resonator, these systems are a perfect fit on your Forester. 

 "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.  

Built entirely in our shop in Woodland, Washington, the Nameless Performance Dual Chamber Exhaust is a direct factory fit to the OEM midpipe on the 2015-2017 Legacy 25i, and features superior quality TIG welded, American Sourced T304 stainless tubing throughout.  

The factory fit flange features laser cut precision, and our in-house Ercolina CNC mandrel bender produces the 2″ stainless primary and secondary chamber tubing, providing excellent breathing characteristics for high end horsepower as well as retaining low end torque.   All tubing as well as the muffler and resonator bodies feature a brushed finish unique to our production process.  

The exhaust tip is polished T304 stainless, constructed of two pieces which are masterfully fit and hand TIG welded in-house.  We have the utmost confidence in our welding department and the results speak for themselves.  

This system also uses our newest twin bar design for each hanger location, and includes a pair of three hole urethane exhaust hanger bushings to isolate rotation and lateral movement of the system at both of the factory mounting points.  The result is a rock solid attachment which prevents side to side motion.  This assembly doubles down on our previous industry-leading gusseted hangers.  Keep an eye on the competition, many of the other systems on the market have no hanger support and simply attach at a single point to the exhaust tube.  We believe the devil is in the details and we pay attention to them.

And as always, our systems include gaskets and top notch metric hardware, two Nameless decals and a Nameless beverage koozie to use after the installation is complete.  Or during, we won't judge.

Recommended Add-Ons:

Urethane Exhaust Hanger Bushings

Our urethane bushings hold your exhaust in place better that the factory rubber bushings and are highly recommended if you race your car or enjoy spirited driving. During hard cornering the exhaust "wags" left to right which sometimes causes the tips to touch the bumper. When this happens there is a chance your bumper can be damaged. The best way to avoid this is to use our urethane exhaust bushings to hold the exhaust in place.

  • 2 Bushings: Replace the two bushings at the rear of the car closest to the bumper. Recommend for those who either drive hard on the street or race occasionally at the track.
