Increase exhaust flow, sharpen throttle response, and elevate the signature sound of the S54 with the Supersprint BMW E46 M3 Stepped Section 1 Front Pipe Set. Engineered specifically for the E46 M3, these 63.5mm front pipes are designed to pair seamlessly with Supersprint stepped headers, creating a properly matched exhaust path that minimizes restriction while supporting stronger performance across the rev range.

Unlike factory front pipes, which can limit exhaust efficiency when paired with performance headers, the Supersprint stepped Section 1 pipes maintain a consistent 63.5mm diameter to promote smoother gas flow from the headers into the remainder of the exhaust system. The result is improved exhaust scavenging, a more aggressive motorsport-inspired tone, and enhanced overall engine breathing while maintaining proper fitment.

Designed and handmade in Italy from premium T304 stainless steel, these front pipes reflect Supersprint’s long-standing commitment to engineering excellence. Since 1955, Supersprint has been recognized globally for developing complete exhaust solutions built around performance, durability, and acoustic precision. Rather than producing isolated components, every Supersprint system is engineered to function as part of a balanced exhaust architecture optimized for BMW M engines.

The stepped Section 1 pipes bolt directly to compatible Supersprint Section 2 exhaust components, allowing enthusiasts to build a fully integrated 63.5mm exhaust configuration from headers back. Integrated oxygen sensor bungs ensure proper sensor placement and straightforward installation, making this upgrade ideal for drivers seeking a refined, high-flow exhaust setup for both street and track-focused builds.
