Rated 5 out of 5 by Ponser Stage IV Kit a Great Enhancement to the Rushmore Engine
Had the Stage IV kit installed during a Biker Build Off event at my dealership. This is a must for the enthusiast that insist on more power with the confidence that the components can be trusted by HD. The Screamin Eagle kit is engineered to work with the 103 engine and bring out the very best the Rushmore has to offer. The Rushmore engine is already an engineering marvel and the enhancement of a Stage IV kit just pushes the envelope to a very manageable and rideable machine. Recommend the dealership installs and have a before and after tuning. Make sure to do a 1000 mile breakend fluid change. I've had my Stage IV for a year without any issues. Check out my Tuning Before and After...documented 116 HP and 116 torque. You will love this Kit!!

Rated 4 out of 5 by TABHOG Should come this way from the factory!
After decades of riding we decided to go with quieter pipes on our current bike. I figured that if I was taking away the bark I should give it some bite so I installed the street stage 4 and Night stick exhaust.
I was hesitant about the increased compression using California pump gas and 259 cams as we predominately are 2 up and loaded down for a few days. We have now put on over 3000 miles and I am very pleased. Yes, as noted in other reviews the engine is noisier at idle and between 2800 and 3200 (maybe I notice more since the exhaust is very quiet). With this set up my dyno shows just above idle the torques is 90 and by 2700 it is above 100 and peaks at 110 at 4800 rpm. HP is around 35 at 2000 RPM and climbs to 111 at 5800 RPM. First club ride we showed up to after the conversion one of our fellow riders looked and said “I see you have the Honda conversion” a little later when we were on some back roads we took off from a stop sign and at the next one his comment was “holy S***t that things a sleeper” . This kit provides a very stable wide power band all the way up. Around town it has gobs of torque with crisp quick throttle response and doesn’t load up. On the open road just twist and go or down shift and really take off. Even using California’s “summer blend” gas there is no pinging or detonating. The only reason I did not rate it a 5 is due to the noise it makes which appears to be and I have been told is normal

If you want some serious power this is what you want. I put the stage4 along with rhineharts slipons and headers and got 120hp/123tor.
