ISR Performance Series II MBSE Rear Exhaust Section for BMW E46 1999-2006
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 1999-2006 BMW E46 3-Series models.
The ISR Performance Series II MBSE Rear Section is engineered to replace the restrictive factory rear muffler with a high-flow, single-exit design. This modular exhaust component provides a more aggressive tone and improved exhaust scavenging, allowing your engine to breathe more freely while reducing significant weight from the rear of the vehicle. Constructed with precision-welded tubing and designed to follow factory routing, it offers a straightforward upgrade for enthusiasts seeking better sound and performance on the E46 chassis.
- Manufacturer Part Number: IS-S2RO-MBSE-E46
- Product Series: Series II MBSE (Modular Build Single Exit)
- Rear section only; designed for modular compatibility
- High-flow piping reduces backpressure and improves throttle response
- Lightweight construction over OEM muffler assemblies
