BMW M3 M4 Decat Downpipes Flexi 3” G80 G82 S58

MTC Motorsport BMW G80 G82 M3 M4 S58 Competition Stainless Steel Decat Downpipes with Flexi 

• The M3 M4 downpipes are machined from T-304 high-grade stainless steel and are tig welded in house
• We have designed these downpipes with a flexi in to provide easier fitment and less stress on the exhaust.
• Provides a sharper throttle response due to faster spool of the turbo alongside noticeable power gains and a much more aggressive exhaust note which sounds truly amazing
• Produces lower temperatures and less exhaust backpressure due to the relief of the turbocharger. The cylinder charge is increased which contributes to maximum performance
• There is also a substantial weight saving in comparison to the factory catalytic converter
• Mandrel-bent for better gas flow and maximum internal size to ensure ultimate performance without the loss of mid-range torque.
• Finished in brushed stainless

• BMW M3 G80 
• BMW M4 G82

We have tested this product and found increases of around 15-20bhp.

Professional installation is recommended as some exhausts sit slightly different from others and can be tight although the feedback we have received from this product is that it is very easy to fit.

We also recommend purchasing a Lambda Sensor Spacer(s) to prevent the engine light coming on in most cases. If you search our other items you will find these. They also have OPF filters with sensors that will need to be coded out by a tuner. We recommend speaking to them before purchasing.
