MTC Motorsport BMW M3 M4 F80 F82 Stainless Steel Decat Downpipes With Hi-Flow 200 Cell Sports Cat and Heat Shield

• The M3 downpipes are machined from T-304 high-grade stainless steel and are tig welded in house.
• Our downpipes come straight from the turbo providing a sharper throttle response due to a faster spool of the turbo.
• They will provide noticeable power gains and a much more aggressive exhaust note which sounds amazing.
• They produce lower temperatures and less exhaust backpressure due to the relief of the turbocharger. The cylinder charge is increased which gives you maximum performance.
• Finished in brushed stainless

These will fit the following models:

• BMW M3 F80 2014-
• BMW M4 F82 2014-

We have tested this product and found increases of around 25-30bhp without tuning and 140bhp+ on a tuned car.Professional installation is recommended as some exhausts sit slightly different from others and can be tight.

OPF may need to be coded out, worth speaking to a tuner before hand to check this with your car.

Note: we cannot guarantee that these will pass an MOT test.
