We are proud to offer our Axle Back exhaust for the 2008+ Subaru WRX STi Hatchback/5 Door and the 2011+ Subaru WRX Hatchback/5 Door. Our goal with this project was to develop a high flowing, low-drone design when combined with a full TurboBack Exhaust.
The result was a 3" into dual 2.25" Axle Back featuring quad single wall staggered tips, all stainless TIG welded construction that is Handbuilt to Order in America. This design also has the benefit of perfectly even flow from the right to left as well as out of each of the four tips. No biased flow here like you may find on muffler designs that use a baffled internal resonance chamber.
Each Axle Back comes complete with a new hardware kit for installation.

For comparison purposes we will use a scale of 1-10 for volume, 1 being stock and 10 being no mufflers.
- No Mufflers: Finally, the sound of the Sedan Muffler Delete for the hatch! We have had people banging down our door for this since we released the original muffler delete for the sedan. This is a 10 on the scale where stock = 0
- 4" Mufflers: This is our new design that uses our in-house mufflers. We build each of these mufflers by hand here in our shop with our usual attention to detail. This "Louder" version uses 2 mufflers that measure 6" long and 4" outer diameter. Despite their small size, these mufflers are extremely effective. The 4" mufflers are louder than the 5" mufflers. This is about a 7 on the scale where stock = 0
- 5" Mufflers: This is our new design that uses our in-house mufflers. We build each of these mufflers by hand here in our shop with our usual attention to detail. This "Less Quiet" version uses 2 mufflers that measure 6" long and 5" outer diameter. Despite their small size, these mufflers are extremely effective. This is about a 5 on the scale where stock = 0
Please keep in mind that we only trust extremely skilled craftsmen to build your parts. Qualified welders who are able to meet our standards in both fit and finish are extremely hard to find and as a result are very expensive. The end result is the highest quality, most functional product that is also a work of art worthy of a gallery.
This will not work with the SPT Dealer upgraded Cat-Back
We include a gasket that combines with the stock gasket to adapt this 3" Axle Back to the stock midpipe.
