Got My D&D 3 1/2" Muffers Installed Today, Man They Sound Great..

Got the 3 1/2" D&D Exaust slip on mufflers with the 2" Vortex baffles installed today. They sound great and fit perfect. The fit and finish of the mufflers was perfect. I also installed the short round billet end caps on the mufflers to keep all looking good with the chrome bumper.

epper:epper:

They have a sweet deep throaty tone to them and a nice bark when throttled. The performance is solid with no hick ups and plenty of power.

No fuel injection mods done. Stock air box with K&N factory replacement filter installed and all seems to be great.

Ride Safe All,

So far so good.

If the air intake is left stock most Harley's since 2009 will take most slip on mufflers available with out any issues. Also the new factory stock air intakes on the 2014 and 2015 Mt Rushmore project bikes takes in 15% more air than the older stock intakes according to Harley. The Harley re-flash to the ECM that is offered at the dealer raises the RPM red line from 5500 to 6200 and makes some very small timing curve adjustments but it does not change the EPA mandated leaner fuel ratio. It only adjust the fuel ratio and air curves plus small timing adjustments to match the added air flow of a stage 1 air intake and filter upgrade.

With the the stock air intake not changed the bike will re-adjust to the factory set fuel ratios in cloaced loop within a few miles of riding after the muffler install. Of course this fuel ratio is still an EPA leaner ratio. The only way to change that is to install some type of fuel controler.

The Freewheeler runs great just like it did before it just sounds a lot better.

I tried to make a video with my phone and it just would not record with any kind of quality. The recording just did not do any kind of justice to the mufflers.

Bellow is a recording D&D Exaust did of them on a 2014 touring model. They do sound very much like this recording.

Nice !! When I changed out the mufflers on the FLRT the guy following me home from the harley shop flagged me over at a stop light on the way home. Said wow that sounds good. I have to agree. No better sound than a happy harley. My personal stereo set.
