680HP Stage 2 McLaren 600LT with Decat Fi Exhaust!

This time I have filmed a McLaren 600LT making some loud accelerations, downshifts revs. This 600LT has been tuned with a stage 2 remap and some catless Fi downpipes. It now got 680HP and 745Nm of torque. Join my Notification Squad: click the Bell ?
