ApexBuilt® BMW B58 Gen 1 Titanium Charge Pipe Kit (2015-19)

Show more
Now including our new, custom designed high-boost capable silicone couplers and T-bolt clamps standard with every B58 charge pipe kit! Make coupler slippage a thing of the past.
ApexBuilt® hand-made titanium charge pipes replace the failure-prone plastic charge pipes BMW F and G-Chassis B58 vehicles 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. 


  • Hand-welded, aerospace grade titanium: connectors, pie cuts, & flanges are CNC GR1 titanium, straight sections use GR2 titanium. 
  • Extremely lightweight, with both pipes totaling only 1.8lbs
  • As of November 1st 2022, ALL units now come standard with 1/8" NPT bungs (with plugs) for easy addition of water/methanol injection
  • Replacement O-ring and C-clip included at no extra cost
  • All required hardware included with purchase
  • Lifetime warranty
