ISR Performance Series II MBSE Exhaust - BMW E46 Early 323/328

The ALL New ISR Performance Series II MBSE exhaust is an incredibly stylish and aggressive exhaust system at an affordable price. Constructed of high-quality stainless steel, the MBSE utilizes dual 2.5" mid pipes that mate to a resonator then a 3" section out to a dual 2.5" tip muffler section. Utilizing our all-new Series II construction, the E46 MBSE features pipe routing that increases ground clearance so you can have a stylish exhaust without sacrificing performance or function.

The Series II MBSE features an extended tip to fit properly with deeper aftermarket aero bumpers and also provides a more aggressive look on stock bumpers.
