MTC Motorsport BMW M3 M4 G80 G82 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 (with heat shield)

These will fit the following models:

• BMW M3 G80
• BMW M4 G82

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.

These should pass an MOT emissions test when fitted. They are road legal and Euro 5 rated.

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