BMW F87, M2 (N55) Catted Downpipe With Heat Shield

Free up your BMW F87 M2 without giving up emissions control entirely. This catted performance downpipe replaces the restrictive factory unit with a high-flow sports catalytic converter and full woven heat shielding.

It delivers most of the gain a catless pipe offers while keeping a working catalyst in the system, which is what makes it the sensible choice on a car that still has to do the daily drive. The sports catalyst keeps the exhaust note cleaner and considerably less raspy than a catless pipe, and dramatically reduces the chance of a check engine light or a failed visual inspection.

Manufactured from premium T304 stainless steel and precision TIG welded throughout, with both factory oxygen sensor bungs retained in their original positions.

Key Features:

High-Flow Sports Catalytic Converter
A far less restrictive catalyst than the factory unit, retaining emissions control while releasing most of the flow a catless pipe offers.

Full Woven Heat Shielding
Wrapped over the length of the pipe, reducing radiant heat into the engine bay and protecting the components packed around it.

Both Sensor Bungs Retained
The pre and post catalyst oxygen sensors both plug straight back into their original positions.

Premium T304 Stainless Steel
High-grade, corrosion-resistant material built to withstand the exhaust gas temperatures a tuned N55 produces.

Cleaner Tone Than Catless
The catalyst takes the hard rasp out of the note, which is the difference between a car you still enjoy on a long drive and one you do not.

Direct Bolt-On Fitment
Mounts to the factory turbo flange and mid section using the original mounting points, with no cutting or fabrication required.

Performance Benefits (When Tuned):

Strong gains in horsepower and torque across the rev range

Faster turbo spool and sharper throttle response

Deeper exhaust note without the rasp and drone of a catless pipe

Far less likely to trigger a check engine light than a catless downpipe

Vehicle Fitment:

BMW F87 M2 (2016-2018)

3.0L Turbocharged N55 Engine

N55 Only - Not the M2 Competition:

This downpipe is for the N55 M2, built 2016 to 2018. It is a single pipe because the N55 is a single-turbo engine.

The M2 Competition (2019-2021) runs the twin-turbo S55 and needs a pair of downpipes, not one — see our F80/F82/F87 (S55) downpipes instead. If you are not sure which you have, the Competition badge on the boot and the quad tips are the quick check, or send us your VIN and we will confirm it before you order.

Please Note:

A high-flow sports catalytic converter is not a factory replacement part. Emissions hardware is regulated and the requirements vary between states, so please check your local regulations before purchasing or installing. An ECU tune is recommended to realise the full benefit of the part, and professional installation is recommended.
