We had the pleasure of working on a 2015 M4, and it’s now revving higher than ever! Fitted with our REVTUBE downpipes featuring 200c European cat converters, along with a customer-supplied cold air intake, this car is performing at a whole new level.



While the decat version of these downpipes is a popular option, our customer wanted to keep the rasp down without sacrificing too much power—so they went with the 200c option.



The results? Stock power of 262kW at the wheels has been enhanced to an impressive 316kW, with torque gains of over 144Nm! The original tune ran a bit too lean, as seen by the torque drop early on, but our custom tuning has brought out its full potential.

Ready to unlock more power in your ride? We’ve got the mods to make it happen.
