BRZ/FRS/86 Dr. Jekyll Axle Back Muffler

Description

WORKS Exhale Exhaust: The WORKS modular Exhale series components allow FR-S/BRZ 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 using the factory OEM exhaust pieces to ensure a precise and perfect fit every time.
The Exhale series 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.
By itself, the gains (~2 HP) are minimal in NA (naturally aspirated) form. Further gains are obtained by including the WORKS MP to complete the cat-back system.
You will save over 11 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:
It looks to me like only the right tip is muffled and most of the gasses will just go out the left tip because there will be less resistance to flow there. 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, we spent a lot 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 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 AB 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.
