2009 street glide, I have installed 3 sets of pipes in the las 30 days. First, the Rineharts, I had them on for one day, the first thing I noticed is I lost my bottom end torqe, the sound was good...loud... and made my radio useless. at this point I had the stock air cleaner and had NOT had a flash done.
Next I tried the new screemin eagle slip on tour mufflers, at this time I also added the stage one air cleaner kit and had the flash done by the dealer to richen up the motor and raise the rev limiter, the sound and growl is only slightly louder than stock. Then I bought the vance and hines monster ovals, these pipe are incredible! the sound is hard to describe...they have a VERY low mono tone, there is not a hint of raspyness, the loundness of the pipes is...well just right. This may just be me but these slip ons provide more low end torque, I had to slow down to 50 mph on the highway and stayed in 6th gear, hit the gas and she pulled strong back up to 70mph. I would have down shifted with all the other pipes. all I can say is I LUV EM!
