Harley-Davidson XR1200 Pipe Comparison

SuperTrapp pipes are made in Cleveland, Ohio, and have offered a unique, patented tunable disc system since 1971. Well known in both automotive and motorcycle circles the tunable disc system allows the tuner to add or subtract discs to tune the powerband and sound of the bike in just a few minutes with basic hand tools. The SuperTrapp system is also made of stainless steel and is a 2-into-2 style that mimics some of the low swept type flat track systems that we have seen on the track lately. Considering that this is a 2-into-2 system that is fairly large overall we were surprised at it being a bit of a featherweight as well coming in at only 14 pounds and eliminated the front OE mounting bracket for an additional 2 1/2 pound savings. We went with SuperTrapp's recommendation of 18 discs for the best all around power and due to the unique design you can add or subtract to move the horsepower and torque curves to suit your riding style and sound requirements. The SuperTrapp did increase ground clearance in the front on the lower pipe but interestingly lost a little under the footpeg area. We aren't sure if this is really a cause for concern but we have heard some riders say they have touched this section on the pavement. The SuperTrapp turned out to make the highest horsepower rating, but did suffer from a torque loss down low.

So after all the testing and analyzing, what did we learn? You'll have to check out the Volume 42 Number 3 issue of HOT BIKE for the results, which include dyno testing, sound testing, weight testing, installation time, and more. The issue is on sale January 12, 2010, so when you pick up your copy let us know what you think!
