ApexBuilt® hand-made titanium charge pipes replace the failure-prone plastic charge pipes BMW F8X M3 & M4 come equipped with from the factory. Our charge pipes are made from a combination of TIG/vacuum welded GR1 and GR2 titanium – lightweight, exceptionally corrosion resistant, and far more durable than aluminum or stainless in performance vehicle applications; with a unique sound and look that only titanium can offer.
