The next step in the evolution is here!
The "Gen 4" series of high-performance sportbike exhaust systems builds on the legend of our industry-changing Generation 3 systems. True race pipes for street use, our new Generation 4 systems provide the same great performance and sound as our proven Generation 3 systems with a stylish, modern look modeled after our best selling Alien Head™ line-up.
With options of four different muffler construction materials, two canister lengths, and two header finishes, it has never been easier to get the perfect look for your bike. Our quietest exhaust systems still provide Brock’s legendary racetrack-proven performance.
