Want more power and noise but still want to hear the stereo????Find a pair of stock take off mufflers and remove the baffles.

As for power, gona need $$$ then you hurt reliability.

 

There is noise and then there is noise. There are exhaust setups that will give you noise all the time and there are exhaust setups that will give you noise when you want them to give you noise. Big difference.

 

Another vote for getting the cat out of the stock head pipe before you do anything else. If you don't want to do it yourself, take it off the bike and take it to a muffler shop or an indy. My indy likes the stock head pipe so he cut a door where the cat is and folded it open. Took the cat material out and then closed the door and welded it back up. Try that or a new head pipe with out cat before you do anything else. You might like the way your slip on's sound now and your done. Nice and cheap. No need to tune.

If you go forward and add the air cleaner, you are going to need a tune. Stick with Fuel Moto to save money. I have a local indy that is a great tuner but if I didn't have him handy, I would be using Fuel Moto because of the great things said about them on this forum and their customer service after the sale. Tell them what you have and they will load a map for you. Change something later and they will update the map.

As you mentioned, you are going to hurt how well you can hear your stereo. It's a vicious loop. You want the bike louder, now you can 't hear the tunes. Now you start looking at amp and speakers. You add that and now the pipes aren't loud enough the cycle starts all over again.

 

Cobra speedster duals (full exhaust, model 6973) are about $550 on Amazon or ebay, or powerport header only (model 6253) are about $450 if you want to use your current slip-ons . The header is a 2-1-2, similar to the V&H power duals or S&S powertune header. The crossover is hidden and the pipe looks like a true dual.

Another option would be a decatted header, ~$100 on ebay.

No matter what, if you replace the header and air cleaner, you will need it tuned somehow. A good tuner if you are not planning on going further than a stage 1 is the Fuelmoto microtuner. If you order from them they will pre-load a map for you. https://www.fuelmotousa.com/i-209229...%20KING%20FLHR

If you really want to save some money and don't mind modifying the exhaust slightly you could order the ones that only fit 2009 touring. I actually ordered these by mistake thinking they were the correct model. Since they were closeouts, I'm not sure I could have returned them. They were so much cheaper that I ended up just modifying them to fit instead of returning them - if I screwed them up I would only be out $215. You will need to either cap the 18mm O2 sensor holes and have a shop put in 12mm O2 sensor bungs at the proper location (what I did, cost me $60 for the bungs and a local muffler shop to drill the holes and weld them on) or somehow use the higher location of the O2 sensor bung with an extension and adapter, or tuner that uses wide-band sensors. If you go this route, make sure to measure and mock up everything when you mark where the bungs are installed - it is close to where some of the clamps go for the heat shields.

I am happy with mine, looks, sound, and power. It is a little different look, not like every other bike. The head shields cover both the header and exhaust so it is one clean line from the header all the way back. It is obviously louder than stock but not obnoxious like a friend's bike that has the true duals from V&H. Cruising and anything under about 2800-3000 rpm it is pretty mild, but louder under hard acceleration and at higher rpm. I installed everything at the same time, so never ran it without the microtuner. It runs well with the tune from Fuelmoto - feels stronger and I will only occasionally get maybe one pop on hard engine braking / deceleration. Mileage dropped a little, but I can still get over 200 miles on a tank.

 

Loud and stereo?

FM Road and track is as loud as you want it to be and just got back from a 200 mile loop jamming on the stock HD 07 tunes the whole time.
