The factory catalytic converters are the biggest choke point in the twin turbo exhaust - removing both frees up real power, spools the turbos sooner, and brings out the aggressive twin turbo tone the S55 was built for.

This is normal for any catless downpipe and not a fault with the part. To run them correctly and keep the light off, the car should be tuned with the rear O2 sensors turned off - any major S55 tuning platform supports this. We strongly recommend installing these downpipes with a supporting tune rather than on a stock vehicle.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOff-road use:\u003c\/strong\u003e Intended for off-road and track use only.
