ISR Performance Series II MBSE Rear Section Only - BMW E36

The Series II MBSE Rear Section is the modular axle-back component that lets E36 owners swap rear styles on the Series II platform without replacing the entire catback. Drop it onto your existing Series II E36 modular mid section to convert the system to the dual 2.5" tip MBSE look.

What It Does

Standalone rear axle-back section of the Series II MBSE exhaust, sold for owners already running a Series II E36 modular mid. The Series II architecture is built so mid and rear sections interchange within the Series II family, letting you change the back half of the exhaust (and the tone profile that comes with it) without buying a full new catback.

Fitment

Rear axle-back section only. Not a complete exhaust system. Works exclusively with the ISR Performance Series II E36 modular mid section. Will not work with OEM E36 exhaust, will not work with the original (non-Series II) ISR E36 exhaust, and will not work with any other manufacturer's catback. E36 chassis restrictions (6-cylinder OBDII, manual transmission, OEM front chassis brace removed) apply through the mid section.
