MTC Motorsport Mclaren Senna Stainless Steel Downpipes With Hi-Flow 200 Cell Sports Cat and Heat Shield. The Senna 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. These will fit the following models.
We have tested this product and found increases of around 50-55bhp 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.
