WORKS Exhale Exhaust Muffler: The WORKS modular Exhale series components allow FR-S/BRZ enthusiasts to quickly and easily add the WORKS ABM (Axle Back Muffler) to the factory mid pipe or the WORKS MP (Mid Pipe) exhaust. All of our jigs are created in-house using the factory OEM exhaust pieces to ensure a precise and perfect fit.
The WORKS Exhale series exhausts are all manufactured in-house using mandrel bends, and includes all of the necessary gaskets, hardware and installation instructions.
Exhale ABM: With the exclusive WORKS Exhale ABM (Axle Back) bolt-on exhaust, it is a straight through design. Features 64mm (2.5") aluminized steel tubing, T-304 stainless steel muffler and beautiful 102mm (4.0") double walled (prevents yellowing and heating bumper cover), T-304 stainless polished tips with the "WORKS" etched logo. The tips are also contoured to follow the lines of the rear bumper. Direct bolt-on to the factory flange and utilizes all 4 hanger locations with OEM-style mushroom end hangers for precise fitment and swaps back to stock in minutes. Includes gasket and simple installation instructions.
This "Dr. Jekyll" version is only for Naturally Aspirated 86's that utilizes a vacuum actuated valve that is closed under low loads such as idle and cruising around while gradually opens as the load (you push harder on the pedal) increases. At WOT (Wide Open Throttle) the valve is fully open giving you the wonderful sound of an unrestricted exhaust!
Plus, you will save over 10 lbs. with the WORKS ABM, but furthermore the volume is very mellow, but not too quiet. Very mild mannered during idle and cruising, but aggressive when you open it up. The tone is a controlled and deep that lets others know your FR-S/BRZ means business!

Q&A:
Will I see a loss of low-end torque?
The AB will not result in a loss of low-end torque. The nice thing about the WORKS 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. |
