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. This catted option provides similar power gains to the straight-pipe option while keeping your car emissions-legal.
 
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 aren't racing, or even if you are but are also environmentally conscious and want to follow the current global green trend, this catted version of our X-Pipe complies with EPA emissions standards so you can feel good and put out serious power. This is also a good option for those who just want to tone down the sound a little. 
 
GREEN Cats - The Real Deal: The GREEN cats used in our catted X-Pipe option are a true premium-quality 300-cell catalytic converter made in North America, meeting EPA federal emissions standards. In back-to-back dyno testing, our catted X-Pipe lost only 7 Hp versus the straight pipe - a fantastic result considering that removing stock catalytic converters on this car typically gains close to 25 Hp. This system, complete with Catted X-Pipe and Longtube Tri-Y Headers, makes more power than any header-back system we've tested - full race, catless, and resonator-free systems included!
  • 300-cell metallic converters with platinum coating
  • 49-State Legal - will not throw an emissions-based check engine light (post-cat oxygen sensors must be extended with additional wiring)
  • 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
