SuperPak Exhaust Pipes From SuperTrapp
Getting A Little Punch From Your Pipes
When it comes to sound, loud may not be what you’re into, but the sound of the H-D stock pipe may not be what you’re looking for, either. A few weeks ago, my dad and I were riding down the coast when we got pulled over in a SoCal beach city where all the cops are ticket-crazy when it comes to motorcycles. When I was pulled over, I knew I was going to get cited, but when the cop started to give my dad a ticket for loud pipes, that’s when the argument started. First off, the cop didn’t even have a sound meter to test the decibels; he just felt that the pipes were too loud. It took us several minutes to show him that the bike was actually stock, with stock pipes.
Anyway, my dad was looking for new pipes to change up the sound without getting too loud, since he just moved into a new condo where loud pipes would be a problem at 4 a.m., which is when he leaves for work. We looked into some replacement mufflers; however, most of the mufflers seemed to offer one thing or the other-power or sound-and most of the time “sound” equalled “loud.”
We found a set of slip-ons from SuperTrapp: the SE Series Slip-Ons, which claim to give a deep, rich, strong sound with less than 3dB (SAE J1287) over stock and an increase in horsepower and torque. SuperTrapp described this as the first step in upgrading your motorcycle. It used to be pipe, re-jet, and an air filter. Now it’s basically the same thing, but with an FI controller for tuning. The company’s selling point is that all the components are made to go together and come all in one box, ready to install. For about $1,000, the SuperTrapp SuperPak comes with exhaust mufflers, SuperTrapp’s pre-calibrated FI control (digital fuel-injection control unit), and a SuperTrapp Pro high-flow air filter.
We stopped at Horn Cycle Works in Pomona, CA, to get the pipes installed and do a few runs on the dyno to see how the pipes performed. Shop owners Curtis Horn and his wife Michelle let us use the shop for the install and testing.
