vance and hines slip on mufflers for road king

Properly tuned, with a GOOD set of pipes, a Screamin Eagle air cleaner or Arlen Ness Big Sucker (very good air cleaner) and proper tuning, you can pick up about 10-12 hp and about the same in torque. If you open up the exhaust, you should open up the intake and let more air in.but.if you do this, you MUST remap the injection to give it more fuel. On top of that, the exhaust bracket on the Sporty's and Softails is also the exhaust cross-over, which helps make torque, eliinate that, you will lose alot of mid-range torque, the mid-range is where most of your riding is done and where you need the power the most.Įveryone wants better sound, but what about making the bike run CORRECTLY, more effieciently, more power.all this will actually make the engine run easier with less strain, it will make it run cooler which will make it last longer. However, The V%26amp H Short Shots are for looks only, they are not good performance pipes at all.they are TOO SHORT and too free-flowing, even with tuning, they will not offer very good perfromance (they also tend to cause exhaust soot build-up on the wheel area). HD's injection will allow for a slight exhaust change with no mods, meaning a Screamin Eagle slip-on muffler, for better sound. I just asked a questions here earlier asking why people make such uninformed decisions when purchasing injection paring the PC and such to Screamin Eagle's SUPER TUNER.read the question info and posts, if you have any questions, email me here through my profile and I will be happy to help. The other two answers are both semi-correct, but there is more info that you should know. This question is being asked ALOT the last couple days. STAY AWAY FROM POWER COMMANDERS!!!!!.Especially on Sportsters and Softails, there is very little room to mount them, and they only control fuel, nothing else.

exhaust it is now going to run over $1100, is all this necessary?09 HD nightster exhaust? The wife has a 09 hd nightster, and wants to change the exhaust to a vance and Hines short shot, no problem, but harley wants to change the intake, retune and dyno test, so to add a $450.
