Axleback Exhaust - 2022+ Subaru WRX - 4" Muffler - 4" Double Wall Tips

Looking for a quick exhaust upgrade to improve the sound and look of your 2022+ VB Chassis WRX?  Our axleback exhaust is a great way to start.  Removing the two factory 13.5lb restrictive baffled mufflers in lieu of a pair of mandrel bent, TIG welded, T304 stainless steel pipes and configurable tailpipe tip style, this system is easily configurable to your desired look and sound level.  Our 4 Inch Muffled Axleback Exhaust featured here comes with 4 Inch Double Wall Tips.

Factory fit laser cut flanges and 2″ dual piping has equivalent flow characteristics of a 3" single straight pipe, providing excellent breathing characteristics for high end horsepower and generating an increase in low end torque (roughly 10hp/11ft lb at the wheels for this and the other muffled axleback options we offer).  Want more torque?  Upgrade to our full catback exhaust later on by purchasing our 3" midpipe.  As always, all of our parts are forward and backward compatible with factory exhaust components and are straightforward to install.  

Fits 2022+ WRX Sedans with OEM or OEM fitment (Nameless Performance) midpipe. 

Each axleback comes with a full hardware kit for installation.

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.
  
  
• 4 Bushings: Replace all 4 rubber bushings on the axleback portion of the exhaust. Recommended for people who race their cars often.
  
  
• 5 Bushings: Replace all 5 of the factory rubber bushings from the midpipe back. Recommended for those who are hard core autocrossers or circuit racers.
