The MTC Motorsport N55 decat will provide a sharper throttle response due to faster spool of the turbo. It will provide noticeable power gains and a much more aggressive exhaust note which sounds truly amazing. It 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. The decat is mandrel-bent for better gas flow and maximum internal size to ensure ultimate performance without the loss of mid-range torque.

We have tested this product and found increases of 10-15bhp.

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.
