Project: MRS3: Conversion MRS3 N4 Rally Exhaust

here we go:
engine cover off:



removed the shield, lambda sensor and attach turbo / catalyst:



removed the under motor hanger, gear oil drained and removed the right axle shaft:



removed the axle shaft bearing block and the catalyst already pulled out:



removed the middle silencer:



before that, cut the pipe between middle and last silencer:



last silencer also removed:



and now to the install of the mrs3 n4 rally exhaust system.
downpipe fixed to the turbo,install the lambda sensor and plug in:





without the original catalyst, there's a lot of space:





mounted the right axle shaft, some brackets and filled in the gear oil:



mounted the shield from the top:



mounted the cover, finish from top:



mounted the middle pipe with silencer and metal cataylist:



mounted the rear pipe:



because the second lambda sensor is mounted further back, I have made a plug&play extensions cord with original connectors on it:



near the gearbox reconnected:



past the steering gear:



clipped in the original conductor holder:

 

to the second lambda sensor:



the hole mrs3 n4 rally exhaust sytem fits perfect. also the tailpipe fits exactly in the middle of the carbon cover without adjustments:



finish:
from the outside it looks nothing. only small hints point to something other sound and performance:
