It is different from the later N63TU \/ N63N slip-on version with integrated outlet bends and lower clamp connections.\u003c\/p\u003e\n\u003cp\u003eA less restrictive downpipe configuration can reduce exhaust back pressure and give the N63 V8 a more pronounced exhaust sound. Changes in turbo response and power depend on the vehicle, the selected version and ECU calibration. No fixed power increase is specified.\u003c\/p\u003e\n\u003cp\u003eThe heat shielding helps limit radiant heat around the downpipes.
