BMW F80 F82 M3 M4 Competition Stainless Steel Decat Downpipes with Flexi
The T-304 high-grade stainless steel downpipes are machined and TIG welded.
We developed these downpipes with a flexi inlet to facilitate installation and reduce exhaust stress.
There is also a significant weight savings over the factory catalytic converter Mandrel-bent for better gas flow and maximise internal dimensions to provide ultimate performance without sacrificing mid-range torque
Because of the turbocharger relief, it produces lower temperatures and less exhaust backpressure.
The cylinder charge is raised, resulting in maximum performance.
Provides a crisper throttle response due to the turbo’s faster spooling, as well as substantial power improvements and a much more aggressive exhaust note that sounds simply wonderful.
Brushed stainless steel finish
These downpipes will fit the following models:
- BMW M3 F80 F82
- BMW M4 F80 F82
- BMW M2 Competition
Please keep in mind that the PPF filters on the M2 competition, as well as the later M3 and M4, will need to be coded out and the sensor removed.
We researched this item and discovered gains of roughly 15-20bhp.
Professional installation is required because certain exhausts sit slightly differently than others and can be tight, despite the fact that this item has gotten positive feedback.
In most circumstances, we additionally recommend acquiring a Lambda Sensor Spacer(s) to avoid the engine light from coming on.
