If you're here you know the stock pipes for the speedy are baby. These are the perfect balance of sound to get you heard on the road but not wake up the whole apartment complex when you start up.
Got the pipes by themselves originally to see if I would really need the additional recommended parts, definitely did so if you're reading this get it all at once to save yourself the time even though they do ship really fast.
When I got those installed (air box removal and air injection removal kit) along with a re-map (Tune 12 from Triumph Twin Power for my '16 speedy) overall performance skyrocketed. Along with sounding even better, the power gains at low rpms make it so much easier to maneuver at parking lot/ neighborhood speeds.
This and the appropriate intake/tune is a must have upgrade for the Speedmaster or America.
Call and talk to them if you have questions! JP hooked me up
