BMW M2 Competition F87 Decat Downpipes with Flexi | Stainless Steel T304 | Catless Turbo Downpipes
Unlock serious performance and sound with these BMW M2 Competition F87 decat downpipes with flexi. Crafted from high grade T304 stainless steel and expertly TIG welded, this catless downpipe upgrade improves turbo spool, reduces backpressure and delivers a harder hitting, more aggressive exhaust note. Expect noticeable power gains of around 15 to 20 bhp in our testing, sharper throttle response and a meaningful weight saving over the factory catalytic converters.
Designed with an integrated flexi section for easier fitment and reduced stress on the exhaust system, these mandrel bent downpipes maximise internal diameter for superior gas flow and performance without sacrificing mid range torque. Finished in a smart brushed stainless look, they are the ideal S55 turbo upgrade for drivers seeking the best balance of quality, fit and value.

Performance and sound
We have tested this product and consistently seen gains of around 15 to 20 bhp, with a crisper, more responsive feel and a deeper, more aggressive exhaust tone that really lets the S55 engine come alive. Customer feedback has been excellent, with many commenting on the quality, fit and the transformation in sound.
Installation and support
Professional installation is recommended, as factory exhaust tolerances can vary and space can be tight. Fitment feedback on these downpipes has been very positive and many find them straightforward to install thanks to the flexi design.
We also recommend purchasing Lambda Sensor Spacer(s) to help prevent the engine light coming on in most cases.
