R2P Downpipe BMW 3 Series G20 (Long Version) – OPF Delete for Gasoline Engines

The R2P downpipe (long version) is designed for the BMW 3 Series G20 with a petrol engine equipped with an OPF particulate filter. By eliminating this restrictive component, it allows much freer exhaust gas flow, which translates into a more immediate turbo response and a notable power gain when combined with a Stage 1 or Stage 2 reprogramming. Made from high-quality stainless steel, it guarantees durability and resistance to high exhaust temperatures.

Key features

• OPF delete: Eliminates the restriction of the original particulate filter, allowing gases to flow unobstructed and improving turbo response.
• Reinforced stainless steel: Robust construction that withstands extreme temperatures and resists corrosion, even under intensive use.
• Reduced turbo lag: The lower backpressure allows the turbo to spool faster, improving acceleration and power delivery across the entire RPM range.
• Direct installation (Plug & Play): Designed to use the BMW G20's original mounting points, with no need for cutting or welding.
• Sport sound: Adds a deeper, more aggressive tone under load, while maintaining discreet behavior at low revs.

Technical specifications

• Material: High-quality stainless steel
• Version: Long (specific for OPF delete)
• Software compatibility: Requires Stage 1 or Stage 2 reprogramming
• Mounting type: Plug & Play (no modifications)
• Finish: Durable polish

Compatibility

Models: BMW 3 Series G20 Sedan
Engines: Petrol equipped with OPF/GPF filter
Years: 2018 - Present

This downpipe directly replaces the original exhaust section containing the Otto particulate filter (OPF) on the latest-generation BMW G20 engines.

Advantages over the original

Unlike the OEM downpipe, which incorporates a dense particulate filter to meet emissions regulations, the R2P downpipe unlocks the engine's true potential. Compared to cheaper alternatives, R2P uses thicker steel, which prevents vibrations and cracks under extreme or track use.

Frequently asked questions

• Is an ECU reprogramming necessary?
  Yes. By removing the OPF, a software tune (Stage 1 or Stage 2) is essential to prevent error codes from appearing on the instrument cluster.
• What sound change can I expect?
  The sound becomes noticeably deeper and sportier under load, while maintaining a refined tone at low revs.
• Is it road legal?
  Parts that remove emissions systems such as the OPF are intended for competition or track use.
