N55 Carbon Dual Air Intake System With Valved Catback Exhaust
Enhance your BMW driving experience with the Turner Motorsport E9X 335i (N55) Valved Catback Exhaust. Designed for hearty exhaust notes and improved performance, this exhaust system offers a subtle factory-like sound with closed valves and a menacing growl when opened. Crafted with Mandrel bent dual 2.5” 304SS pipes and a high-flow valved stainless steel muffler, it ensures efficient gas flow.
The kit includes Turner Mid Pipes, a Valved Exhaust, Muffler Valve Controller Kit, and engraved Exhaust Tips. Accuseal slip-fit joints simplify installation, making it a bolt-on replacement for the OE version. The full exhaust system is available as Axle Back, Cat-back, or a full Turbo back system, providing a dual-purpose solution for both your neighbors and your desire for volume.

Upgrade your N55 engine with the Turner Carbon Intake, breaking away from common setups. The dual inlet design adds functionality without compromising engine bay aesthetics. Located in the "sweet spot," the second inlet maximizes airflow and lowers intake air temps. The bellmouth velocity stack design reduces turbulence for a satisfying flutter after throttle release. The carbon fiber airbox and intake tube feature a gloss clear coat for UV protection, offering a beautiful OEM+ upgrade.
Turner Carbon Fiber Intakes are CAD-designed, ensuring optimal airflow improvement over stock. The kit includes a Carbon Intake Tube, Full Carbon 2 Piece Airbox, Bellmouth Velocity Stack Cone Filter, Billet Turbo Inlet Adapter, Silicone Coupler, and Hardware for Installation.
