High flow downpipes for the BMW S68 V8

Increase power, improve turbo response and amplify exhaust character with the Boosted Engineering High Flow Downpipes for the S68-powered X5 M and X6 M LCI, X5 M60i and X6 M60i, and the G90 M5.

Designed to reduce exhaust backpressure and improve turbocharger efficiency, these downpipes help lower exhaust gas temperatures under load while improving overall engine performance and responsiveness. Expect a significantly more aggressive exhaust note with increased turbo sound and sharper throttle response.

When paired with appropriate tuning, improved cruising efficiency and reduced fuel consumption may also be achieved under light throttle conditions.

Suitable for stock turbo and upgraded turbo applications.

FAQ

Will these fit my pre-LCI X5 M or X6 M?
No. Pre-LCI F95 X5 M and F96 X6 M cars use the S63 engine. See our S63 X5M / X6M downpipe for those.

Do these fit the F90 M5?
No. The F90 M5 uses the S63. This listing is for the S68 G90 M5. See our S63 F90 M5 / F92 M8 downpipe.

Do I need a tune with these downpipes?
Yes. ECU calibration is strongly recommended after installation to maximise performance, drivability and reliability.

Is there a high flow cat or heat shield option?
Not for the S68. These downpipes are catless only.

Is it road legal?
Removing the catalytic converter can affect emissions compliance and roadworthiness. Check the rules in your state before fitting.
