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.
These are a must for any big HP build. Pair with our ECU Tuning for maximum results.
