To test our reputation, wethought it would be exciting to runour new \"Double Header\" 4 into 2system against the best of our com-petitiors\' 4 into 1 systems—\"headsup\"—at the dragstrip. The resultswere amazing!We used a new, fuel injected Kaw-asaki Z-l Classic as the test bike and,after some minor tuning*, we pro-duced a baseline time of 11.97seconds at 111.51 MPH-stock. Wethen bolted up the systems, one at atime, and made five passes with eachsystem. The best times are as follows:
Lastly, just for comparison, we ranour own 4 into 1 at 11.44 sec and119.04 MPH—that\'s PERFOR-MANCE!The \"Double Header\" system fea-tures a high velocity 180° firingdesign for excellent smoothness andthrottle response, as well as a bal-anced look to your machine. The ex-haust note is crisp, yet mellow to theear, and the styling is Jardine sharp.Another plus—our individual pipedesign means a better finish and inex-pensive repairs if you damage justone tube—you don\'t have to buy thewhole header.Horsepower and quality—that\'sJardine!*A11 test machines are prepared and ridden byprofessionals, using proper safety equipment.Documentation and tuning specsare available upon request.7142 BELGRAVE AVE.GARDEN GROVE, CA 92641
