ISR Performance Series II - Resonated Mid Section Only - BMW E46 Late 325/330

The ISR Performance Series II resonated mid section for the BMW E46 3 Series (late, 2002-2006 body) is part of ISR's modular exhaust line. Every Series II piece shares the same flanges, so you can mix and match mid sections and rear sections to get exactly the sound you want.

This is the resonated mid section only, the center pipe that runs from the factory downpipe or cat to the rear section. It includes a straight through resonator that takes the rasp out of the note. Combine it with any Series II rear section (EP Dual, EP Single, GT or MBSE) to build a complete cat-back, or add it to a rear section you already own.

Built from T304 stainless steel with TIG welded joints and 3 inch piping (2.5 inch on BMW), the Series II line bolts to the factory hangers and mounting points with no cutting or welding.
