WORKS Exhale Exhaust: The WORKS modular Exhale series components allow FR-S/BRZ/86 enthusiasts to quickly and easily mix and match the MP (Mid Pipe) and ABM (Axle Back Muffler) with any of the factory exhaust components. All of our jigs are created in-house utilizing the factory OEM exhaust pieces to ensure a precise and perfect fit every time.

The Exhale series are all manufactured in-house here in California, using mandrel bends, and includes all of the necessary gaskets, hardware and installation instructions.

Exhale ABM: The exclusive WORKS Exhale ABM (Axle Back Muffler) bolt-on exhaust is a straight through design. Featuring 64mm (2.5") aluminized steel tubing, a T-304 stainless steel muffler, and beautiful 102mm (4.0") double walled (prevents yellowing and heating bumper cover), T-304 stainless polished tips with laser etched "WORKS" logos. Additionally, the tips are contoured to follow the lines of the rear bumper. The Exhale ABM is a direct bolt-on to the factory flange, utilizing all 4 hanger locations with OEM-style mushroom-end hangers for precise fitment and can be swapped back to stock in minutes. Includes gasket and simple, easy to follow installation instructions.

By itself, the gains (~2 HP) are minimal in naturally aspirated form. Further gains are obtained by including the WORKS Mid Pipe to complete the cat-back system.

The WORKS ABM nets over 11 lbs. in weight savings! The volume is very mild mannered during idle and cruising, but aggressive once you open it up. The tone is deep and controlled, letting others know your FR-S/BRZ means business!

Q&A:

It appears that only the right tip is muffled and most of the gasses will just pass through the left tip due to the lower resistance. Is this correct and are there any issues from this?
That is correct that one side passes through the muffler and the other does not. That said, our team spent extensive time tuning the left side outlet size (it is slightly downsized) to achieve a good balance between the sound and flow through the two outlets. This results in both outlets being fully functional. The design allows for simplicity in construction, smaller packaging, and weight savings; all while still producing the same power gains as a straight pipe in naturally aspirated cars.

Will I see a loss of low-end torque?
The ABM will not result in a loss of low-end torque. The nice thing about the exhaust is that it makes a little bit of power everywhere throughout most of the RPM range. Not just at the peak or one area.
