BMW X5M F15 & X6M F16 Cat Delete Downpipes 3.5" -Velocity AP
£1,470.00 (Inc VAT)

The S63B44T2 4.4 liter V8 engine in the X5M and X6M packs a powerful 575 hp and 553 lb-ft of torque. The most powerful AWD platform BMW has ever made. But with two huge catalyst bricks per exhaust bank, a lot of backpressure is created, increasing engine bay heat, restricting airflow and performance and limiting spool speed on the turbos.


VelocityAP has designed the first 3.5" to 3" hybrid cat-less downpipe for the F15 and F16. Utilizing 304 Stainless throughout for supreme heat resistance and durability, and a smooth 3.5"-3" taper for minimal turbulence and restriction.


Removing the catalysts dramatically improves the exhaust sound, letting the V8 breathe.
