Go to your friendly local welder or exhaust specialist and ask him or her to add 6" to the rear of each of your mids. Ask your welder to use the same diameter pipe and to heat/mechanically expand it to fit over the cut midpipe before welding. This way, your newly extended mid will fit inside your Supertrapp inlet without issue. | Go to your friendly local welder or exhaust specialist and ask him or her to add 6" to the rear of each of your mids.

Paint your completed mids and stock clamps with [[I want to repaint my exhaust pipes | Paint your completed mids and stock clamps with [[I want to repaint my exhaust pipes|exhaust paint]]. You could powder coat them, but it's pricier. Another alternative is to use exhaust wrap on your mids, which has aesthetic and scientific merit, some believe. Others believe it merely makes everything rust quicker. | ||

====Owner reaction==== | |||
After several rides: With five discs in each can, a properly tuned stock motor idles steadily at about 1300 rpm, has crisp throttle response off idle, and no flat spots. This seems to be a very happy bike. | |||
Thanks to the hard rubber mounting fixtures to the rear peg brackets, there is virtually no vibration, and the stainless cans dissipate heat very effectively. Moreover, though the bike is louder than stock, it's not annoyingly so - one could still easily have an Ipod bud in one ear - and there are no unpleasant or jarring tones at any rpm. The bike's sound is reminiscent of a 90-degree V-twin... like a small-displacement Ducati Monster. | |||
