One of my favorite pipes ever has got to be the Supertrapp 2 into 1 setup with the tuneable discs. This pipe combination is just a dynamite homerun combination for me personally. I absolutely love the 2 into 1 design both for the looks that it provides and the useable power increases they provide.

I am just one prod away from installing a pair of the Supertrapp 2 into 1 pipes on my 2007 FXSTB and replacing the D&D Fat Cats with it. I am not unhappy with my Fat Cats but they are not compatible with a lowered bike and my bike is slammed in the weeds. I like the lowered look too much to give it up so I need to make a change to the pipe.

Supertrapp Fit and Finish

Supertrapp cut its teeth in the superbike world and have been making pipes forever. Think Kerker and you should recognize a familiar cousin. Supertrapp uses all of the same tricks that the other manufacturers use such as a stepped pipe diameter, blue proof heat shields, and high quality fit and finish but their biggest advantage is the tuneable disc setup that has made Supertrapp famous.

ANY pipe will require a LOT of dyno tuning in order to maximize its power potential and many expert tuners will modify your pipes, drill them, weld on them, use cones, change baffles etc all in the name of tweaking just the right combination. With Supertrapp you don't need to do any of this, you simple adjust the number of discs in the endcap to tune both the powercurve and the sound of the pipe.

I have included a copy of an installation review that I found on the internet so you can see how simple the installation was for these pipes. They really don't install any differently than any other set of pipes for your Harley. That is one thing I love about HDs, they are simple machines and very easy to work on.

Supertrapp 2 into 1 Power

Supertrapp's will produce great power across the spectrum and it isn't uncommon to see gains of 10 hp and similar torque numbers as well. The best part is that the power will come in the useable power curve, aka the rpm band that you will typically operate your motorcycle in.

Your gains will be more dramatic too depending on the original state of tune that your bike was in and the level of modifications that you have installed on your bike.

The install below includes some dyno charts at the bottom of the page so make sure you check them out before you go. If you're looking for a great 2 into 1 pipe then I would give the Supertapp 2 into 1 a good look, I know I am and fully expect to be sporting a pair of these on my Nightrain before too long.

Ok you're almost home. As you can see installing a set of pipes on a Harley Davidson is really quite simple and can be accomplished with basic hand tools.

Supertrapp 2 into 1 Dyno Results

Without getting overly carried away with tuning the pipe or the race tuner, at this point we gained an impressive 10 more horsepower and 6 more foot pounds of torque.

The most significant of those improvements were in the torque curve from around 3,500 to 4,500 RPM. This was a nice gain to the mid range and will make the bike fun to ride. Overall, our best numbers came in at 77.57 max. horsepower and 78.22 max torque.

Riding Impressions: Right off the bat I was very pleased with the look of the SuperTrapp 2 into 1 system; in spite of the fact that I’m not a big fan of crossovers or true duals. Once I fired it up I realized the sound had changed considerably. The tone is real good and very distinct to SuperTrapp. It isn’t annoyingly loud at idle or low RPM, but at the same time, opens up real nice when you get on it. As I headed out to the highway, I noticed that the bike had a lot more pull.

Going up through the gears, I felt that it got up to speed faster and the engine wasn’t working as hard. When I came off the exit ramp, after about 60 miles or so of highway time, there was no pop on deceleration. I have about 500 miles on this system now and the powdercoat is holding up real well. We plan on doing some further tuning to the disc system on this pipe, but for now we decided to stick to SuperTrapp’s suggested starting point.
