Thinking of upgrading my stock mufflers, 2004 Road King. Who has installed American Custom mufflers ? Are they a quality product and how much better than stock is the sound?

 

I've installed their slip-ons on 2 previous bikes. Both times I ordered pipes from them and then sent mine back and both times the pipes I received were as-new. And their sound is perfect - nice and deep with no decel popping. They're hard to beat for sound and price.

 

I've got em. run the mid baffles but I drilled the same no. of holes em as they came with. I get a nice deep tone and the more throttle the louder they get. I creep out of the of the neighborhood and bother nobody. I can gear down or give throttle and raise the dead. I like mine' and didn't have to sell my first born to getem.
kroozeabout.

 

Their quality is excellent as they use the Stock Harley slip ons as their base. They remove the stock baffles and replace them with interchangeable slip in baffles. You can make your bike quiet, loud or LOUD! by deciding which baffles you choose to install.

Some like them loud for riding around town with friends, and then change them to quiet for longer road trips.

Seems like the louder you make them, the more power you get from the engine.

Least expensive way is to send them you pipes, and they will modify them and return them back to you.

 

I had their true dual head pipes put on last Fall. Top notch. They had their new line of mufflers on display and they were top notch. I didn't buy them only because I am happy with the BUB slip ons that I have.

While I was waiting I spoke to the owner. A real nice guy that is proud of the products that they sell.

 

I have had mine for about 7 months, and I love them. I ordered the slightly blemished bombers for my 2009 Road King with no baffles. I received the slip ons in just about a week, and I changed them over my lunch break. I already had the 1st one on before I remembered that I had ordered the slightly blemished set. I had to hunt down a few little marks here and there. It is amazing how they went away when I mounted them on my bike too! I think the install time was 38 minutes from start to finish.

I love the deep sound, and now cars don't try to merge into me!

 

i have them and like them. good sound and chrome.

 

I installed a pair of Bombers on my 09 Road King. Without a baffle WAY TO LOUD, mid range baffles worked well. You might want to drill extra holes to louden/deepen the sound as others have stated. With just their slip-on (no filter change) the bike developed a slight decal popping. I installed a V&H Fuelpak, problem solved.

 

They make a true dual?

 

Yep, have them on my Road King.
