Fitment Note
The KYOSTAR Muffler Delete Axleback Exhaust is intended for compatible 2022+ Subaru WRX applications.
An axleback exhaust replaces the rear section of the exhaust system, typically including the factory rear muffler assemblies and associated tailpipe sections.
This product features a muffler-delete configuration. Unlike a conventional muffled axleback, it does not use traditional rear mufflers in the visible exhaust sections.
A muffler-delete configuration can increase exhaust volume and change exhaust tone compared with a factory muffled system. Actual sound depends on the vehicle's complete exhaust configuration, operating conditions, and installed modifications.
The supplied product information identifies four 4-inch polished-finish tips. The exact measurement method for the 4-inch specification is not separately documented.
The product image shows left and right axleback sections with dual polished exhaust tips on each side.
The supplied specifications do not establish the exact main pipe diameter, stainless steel grade, wall thickness, measured sound level, or verified horsepower and torque gains.
Exact included clamps, gaskets, bolts, and other installation hardware should be confirmed before purchase.
Professional installation is recommended. Verify all exhaust connections, hangers, and exhaust tip clearances before road use.

The KYOSTAR Axleback Exhaust combines stainless steel construction, four polished exhaust tips, and a muffler-delete layout for a sportier rear appearance.
The polished exhaust tips provide a classic metallic finish that complements the WRX's quad-exit rear bumper design.
