• Bimmerworld E9X M3 Longtube Headers

    E90 / E92 / E93 M3 - LHD Only




The BimmerWorld Longtube Headers produce results and are guaranteed to surpass expectations. The true equal-length header changes the shape of the exhaust sound, eliminating some of the muddiness of mismatched exhaust pulses for an intoxicating, crisp, and harmonious note. 

  • Tri-Y Design - Cylinders are paired properly to assist in exhaust scavenging to maximize low-end torque and area under the curve with no loss in high-end horsepower
  • Stepped Primary Tubes - Primaries step from 1-5/8" to 1-3/4". The smaller diameter boosts low-end torque while the step to the larger diameter in the primary frees the exhaust gasses for higher RPM flow.
  • Merge Collector - 2" secondary pipes flow into a merge collector with a 2.5" venturi and 3" tailring to promote scavenging.
  • Precision Production Fixture - Production fixtures are laser cut and exceedingly robust, with contact points every few inches to ensure the part you receive fits perfectly as designed. 
  • Laser-Cut Flanges - Flanges are precision cut from thick 3/8" 304 stainless stock to retain shape, with voids for weight reduction.
  • Mandrel Bent Tubing - One-piece tubes are solid formed instead of pieced together for smoother exhaust gas flow and long-term durability.
  • Band clamp attachment maximizes underbody clearance and makes exhaust removal and installation quick and easy.
  • Full 304 Stainless Steel construction for heat retention, durability, and corrosion resistance.
  • Full lifetime warranty against defects in materials and craftsmanship.

Base Run (Green Line) - Pure stock car with an aftermarket rear muffler (same piece used for all tests). No software or any other modifications.

Stock with X-Pipe (Blue Line) - Same stock car with our BimmerWorld Non-Catted, Race X-Pipe, adapted to fit the stock headers. Additionally, we tuned the car with a custom Epic Motorsports calibration to provide the best possible result achievable with stock headers and an otherwise stock car.

Headers with X-Pipe (Red Line) - The only change for this run was installation of our Longtube Tri-Y and a proper software calibration for the hardware change. So what do the headers do? A flat torque curve with improved power throughout the rev range, and peak gains of 41Hp and 32ft-lb over stock and 11Hp and 11ft-lb over our best-case stock header system!

Fits all left-hand drive E9X M3 cars - will not fit RHD models.
