Harley exhaust test. Samson vs Jackpot
2003 Harley Electra Glide with stage 1 air cleaner and power commander.
1st test- My old Samson Rolled Thunder slip ons with power commander map from their homepage.
2nd test- New Jackpot 4" Dyno tuned slip ons with a power commander map provided by Fuel Moto (maker of the Jackpots).
Both tests conducted on same day under same conditions. Camera is approx. 12 feet back. Idle and 2000-2500 rpm. Bike runs much smoother on the Jackpots and has a nice deep tone that is not too loud.
