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 growl these SUVs were built to make. Designed specifically for the F97 X3M and F98 X4M from 2019 to 2026.\u003c\/p\u003e\n\u003cp\u003eExpect \u003cstrong\u003e+30 to +50 horsepower with a supporting tune\u003c\/strong\u003e (more on big turbo builds), dramatically faster spool, and sharper throttle response.

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 S58 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.
