BMW M3 F80 Catless & High-Flow Catted Downpipes — S55 3.0L Twin-Turbo Inline-6 | 2015–2018
YPG Motorsport race downpipes for the BMW M3 F80, replacing the factory catalytic converters with unrestricted or high-flow alternatives. The S55 engine responds aggressively to reduced backpressure — expect sharper throttle response, faster turbo spool, and a deeper, more raw exhaust note immediately after installation.
Available in three configurations: fully catless for maximum flow on track-dedicated builds, 200-cell high-flow catted for the balance of performance and reduced smell on spirited street cars, and 400-cell GESI catted for emissions-compliant builds that still want measurable gains.
- Material: SS304 stainless steel, mandrel-bent, TIG-welded
- Fitment: BMW M3 F80 (2015–2018), also fits M4 F82/F83
- Engine: S55 3.0L twin-turbo inline-6
- Power gains: +20–40 WHP (catless with Stage 2 tune)
- Warranty: Lifetime warranty against manufacturing defects
Stage 2 ECU calibration is strongly recommended with catless downpipes to prevent CEL and optimize fuelling. Pair with an Eventuri S55 intake for a complete bolt-on power package.
Ships worldwide from YPG Motorsport — free shipping to the GCC, USA, UK, and EU.
These downpipes are the hardware prerequisite for Stage 2 power. Pair them with the matching ECU tune to extract the full gains.
