ALPINA B3 S (E46) 3.3i 2003 -> 2005

aka: Performance sport exhaust for ALPINA E46 B3 S


Supersprint is world known as the Performance exhaust specialist for all of the Alpina models, both classic and current.

The 2003 - 2005 E46 B3 S, being the most powerful BMW E46 ever made with the S52-based engine, is no exception.

This 3.3l larger displacement motor greatly benefits from the Supersprint long tube stainless headers and front section, built with HJS Motorsport, high-flowing catalytics.

We have developed specific, distinct headers for the LHD and the RHD models, with Oversize diameter primaries, using special flanges, precisely machined to retain Alpina's secondary air injection system.

This feature ensures that the Supersprint exhaust won't alter the emissions, with no side effect on the flowing carachteristics.

Our full system guarantes major gains in performance, a gorgeous sound, and an unlimited durability.

We feel confident in saying that the Supersprint exhaust is the most effective modification, and the best long-term investment for the now become classic Alpina E46 B3 S.

A full system is also available for the 1999-2002 E46 B3, and for the AWD B3 / B3 S models as well.
