ISR Performance 2015+ Subaru WRX MBSE Type E Catback Exhaust

The ISR Performance MBSE Type E cat-back exhaust for the 2015 and newer Subaru WRX is a quad tip stainless system that starts with a 3 inch mid pipe and splits through a Y pipe into dual 2.5 inch muffler sections. Each rear muffler carries two 3.5 inch tips, giving the VA WRX the full quad exit look along with a deeper exhaust note and less restriction than the factory system.

Specifications

• Stainless steel piping throughout
• 3 inch mid pipe
• Y pipe splitting to 2.5 inch muffler sections
• Two mufflers, each with dual 3.5 inch tips (quad tip layout)
• Adapter flange for direct bolt-on connection to the factory downpipe

Application

2015+ Subaru WRX. The donut gasket adapter lets the 3 inch mid pipe bolt to the stock downpipe, so the system works with a factory downpipe or an aftermarket downpipe that retains the OEM flange.

In the Box

• 1x Mid pipe
• 1x Y pipe
• 2x Dual muffler sections
• 1x 2 bolt donut gasket adapter
• 1x Donut exhaust gasket
• 2x 2 bolt 3 inch exhaust gaskets
• 2x 2 bolt 2.5 inch exhaust gaskets

Install Notes

Hang all sections loosely first, then center the tips in the rear diffuser before torquing the flanges. Use the 3 inch gaskets at the mid pipe joints and the 2.5 inch gaskets at the muffler sections. On an FA20 WRX with an aftermarket downpipe, confirm the downpipe uses the stock two bolt flange so the included adapter lines up.
