Horsepower/torque gain for touring slip-ons
Have any of the bike magazines done a horsepower/torque gain test for any of our touring bikes? I remember Motorcycle Cruiser doing one for the Yamaha Roadstar back around 2000. They took each aftermarket exhaust system and dyno'ed the bike and published the HP/torque gain or loss. The bike dynoed was a stock machine and some of the systems actually lost HP/torque. This would be a great job for one of our Bagger magazines.

One of the mags did a test about a year and a half ago on 6 or 8 slipons.
The Supertrapp SE's were at or near the top in sound, tq, and hp.
I had already purchased another brand, however.
Stage 1 with a tuner should net you about 15% more hp, 10% more tq.
That's what it is on my 07 and seems to be consistent with others.

Generally you'll get the best HP/TQ gains with either a 2-into-1 system or Fuel Moto's Jackpot mufflers. The latter uses stock head pipes, and with a PCIII, Jamie's map, and a FM AC may be the best bang for the buck available. It is much cheaper than a 2-into-1 system and has a nice, deep tone that doesn't wear on you or drown out the radio.
True duals will hurt both HP and TQ numbers, but some prefer their stereophonic sound qualities.

I just did Rineharts Stage I and Air cleaner. Got it back 2 days ago and tinight I finally ran it hard and WOW what a diffference!
Getting on the highway I was doing 70 in 3rd gear in a split second it seemed. Much better performance than my 06 RG ever had and I had stage I, air cleaner and V&H True Dual longshots.
