The BimmerWorld View - Upgrading to our BimmerWorld E9X M3 Longtube Tri-Y Headers? To complete the package and maximize performance of your system, you'll also need our X-Pipe. The 3" construction maximizes airflow in the hottest part of the system where it's most critical, and the X merge is engineered to optimize flow and scavenging. 
Our BimmerWorld E9X M3 X-Pipe is designed to perfectly complement our Longtube Tri-Y Headers - this piece does not bolt onto stock headers.  We've duplicated the architecture and design that we developed on our E92 M3 race car to maximize both flow and scavenging effect. The X crossover component is the same as the piece we race with, positioned for optimized power output and tucked tight to the chassis to maximize ground clearance.  The 3" inlet and main pipes keep the hottest exhaust gasses flowing while the step to 2.5" toward the back retains velocity as the exhaust cools.
If you're building a race car, the choice is easy - you want the lightest, highest-flowing piece with the lowest price tag, and this straight-pipe option of our X-Pipe sheds unnecessary weight and minimizes flow restrictions. Plus, it adds volume to your exhaust system - if you happen to need a little more cowbell from your S65 V8.  

  • High horsepower handling - supports applications up to 800 Hp
  • Handles exhaust temperatures up to 1,500° F
  • Ideal for street-legal supercharged M3s as well as naturally-aspirated engines
