CTS Turbo High-Flow Catless Downpipe For BMW 230i / 330i / 430i / 530i (B46 Engine) F-Chassis & G-Chassis

Description

Upgrade the performance and sound of your B46-powered BMW with the CTS Turbo High-Flow Downpipe. Designed as a direct drop-in replacement for the highly restrictive factory downpipe, this premium component is engineered to maximize exhaust flow, dramatically reduce backpressure, and allow your turbocharger to spool up significantly faster.

Fabricated from premium TIG-welded T304 stainless steel, this downpipe guarantees superior durability, corrosion resistance, and thermal capability. By eliminating the factory catalytic converter restriction, you will experience a noticeable increase in horsepower, torque, and throttle response, alongside a much deeper, aggressive, and throaty exhaust note that truly unleashes the character of your 2.0L turbo engine.

Key Features:
– Material: Constructed from high-quality, mandrel-bent T304 Stainless Steel.
– Construction: Precision TIG-welded with CNC-machined flanges to ensure a perfect, leak-free fitment.
– Performance Gains: Greatly improves exhaust flow, unlocking significant horsepower and torque when paired with a tune.
– Sound Profile: Delivers an aggressive, sporty exhaust tone with enhanced turbo spool sounds.
– Fitment: Direct bolt-on installation replacing the OEM downpipe. Fully compatible with both RWD and xDrive models.
– Mandatory Note: An ECU tune (remap) is strictly required after installation to optimize engine performance and eliminate “Check Engine Light” (CEL) warnings.
– Disclaimer: This product removes the factory catalytic converter and is designed exclusively for off-road, track, and motorsport use.
