With an unwavering commitment to both price and quality, we adhere to a "customer-first" standard, ensuring that our products exceed expectations without compromise.

Performance

The factory downpipes on your BMW 335Xi are equipped with restrictive catalytic converters that hinder exhaust flow and create back pressure. By replacing them with our 3" n54 catless downpipes, you'll significantly reduce back pressure, leading to faster turbo spool, increased power and torque, and a more aggressive exhaust note. This upgrade is ideal for running higher boost levels and Stage 2 tunes, providing a substantial performance boost and enhancing your driving experience.

Construction

• Material: Crafted from 3" mandrel-bent stainless steel, transitioning to 2.5" to seamlessly connect with OEM midpipes.
• Fitment: Designed specifically for the AWD N54 platform to ensure a perfect fit.
• O2 Sensor Bungs: Equipped with two O2 sensor bungs for remounting factory sensors and maintaining air/fuel mixture monitoring.
• Tune Required: As these are catless downpipes, an ECU tune or CEL fix is necessary to avoid a check engine light.
