ISR PERFORMANCE - SERIES II - MBSE Resonated Modular Cat back exhaust system - BMW E36

The ISR Performance Series II MBSE Resonated Catback for the BMW E36 is a full modular exhaust system built on the Series II architecture. Dual 2.5" mid pipes feed a resonator, then a 3" section out to a dual 2.5" tip MBSE rear. Aggressive tone, refined enough not to drone, and pipe routing designed for ground clearance.

What It Does

Complete catback replacement for the E36. The Series II construction routes the piping to increase ground clearance versus older designs, the resonator keeps highway cruising livable, and the extended MBSE tip clears both factory and aftermarket aero bumpers cleanly. Because the system is modular, you can later swap the MBSE rear for the EP Dual rear (IS-S2RO-EPD-E36) without buying a whole new catback.

Fitment

BMW E36 OBDII 6-cylinder, manual transmission only. Will not work with automatic transmission. The OEM front chassis brace must be removed for installation. Not backward-compatible with the original (non-Series II) ISR E36 exhaust.

What's in the Box

• 2x flex mid pipes
• 1x resonated mid section
• 1x MBSE rear section
• 1x gasket and hardware pack
