The American Custom Tone-Flex System will change your riding experience forever. With incredible sound, great performance, and the flexibility to change your sound and tone in minutes, you'll take your pipes to the next level.
American Custom uses a unique design that allows you to attach a range of baffles to your exhaust pipes to control sound and performance. Baffles are easily attached, and you can change them out at any time. By customizing your original Harley pipes, we save you money while allowing you to maintain the highest quality in craftsmanship and finish. Certain models are equipped with a fixed performance baffle system. The baffles on these are not adjustable. However, you will love the low, deep tone that they produce!
The American Custom Tone-Flex System is comprised of re-fit Harley parts in an effort to protect the environment and provide the highest quality materials.
What our customers are saying
Got my pipes Thursday. Black Slash Down Bombers. From the time I opened the box until they were on the bike took about 20 minutes.
I started the bike, and at the moment my Harley purchase was complete. Great sound, it is like the slip-ons are screaming "POWER"
The wife came home a few minutes later so we took a quick ride to run to the store. Every time I gave it gas I could hear her in the back laughing. At that point I knew we had gotten the right pipes from the right people for the bike.
Thank you for making such a great product. I will be looking at the Power Flex header with my refund on my old stock slip-ons....

I ordered my "less than perfect" pipes and found the flaw. I put them on and the flaw "disappeared". I fired up the bike and my concerns about how they actually sounded (relative to the sound on the web site) also disappeared. The sound is awesome. They arrived Wednesday afternoon and were down on Beale Street for bike night that evening. My riding partner (who had recently purchased the same type pipes from a competitor) spent the evening saying "man I wish I had found that site when I bought mine", They sound better and cost less. Great product, great service, great price. Congratulations American Custom. Your name is being spread!

"Incredible" is the only word I can use to explain the sound from my American Custom Exhaust. I am thoroughly impressed with everything from the fast shipping time to the phenomenal quality of the product. I've had several Harleys and have owned Vance & Hines, Rineharts and Screamin' Eagle pipes and I can honestly say that none sound anywhere close to the clean, deep rumble of the American Custom (exhaust). Thanks very much to everyone at American Custom Exhaust!

I received my mufflers back for my 2007 HD Classic Ultra Glide. When American Custom says you get them back in 3 days folks.......they mean 3 days. I couldn't believe it. My husband had them on the bike by the time I got home from work. I couldn't wait to start the bike. THE MUFFLERS SOUND SO MUCH BETTER THEN THE SAMPLES you hear online. I am soooo happy with the results! I took the bike out right away. I couldn't help but smile the entire time I was on the bike. Thank you soooo much. I will definitely be telling everyone about you!

To all you guys at american custom....
I have to tell you...the work you did on my street glide mufflers is nothing short of amazing. The best way to explain it is...it's kinda like when your walking down main street at Daytona Bike Week, and ya can hear that engine running from someone who just started their machine...and all you can think to yourself is...that's what I wish my bike sounded like. The growl when you tweek the throttle, the low rumble when it sits idling... not to mention the added feel of power behind the throttle. Nothing less than amazing in every respect...
I installed your headers (competitors were in the $450 to $650 price range) on my 2010 Harley Ultra (FLHTCU). I then installed the appropriate map in the PC V and all I can say is thank you. The heat from the catalytic converter is gone, the sound is better, the bike pulls better, and my fuel economy went up 4 MPG. Nice to know American ingenuity is still out there!

The boxes arrived and I used almost the full 30 days before returning the cores due to waiting for weather to become bearable to ride in so I could fully test them out. The pipes were easy to install and sound great. They are loud enough to get attention but not obnoxious to those around you. Being in Law Enforcement I still want to set a good example and be safe to boot. The power increase is nice and no additional changes were needed. Thanks for your help and the folks that took my order. They were very friendly and knowledgeable making it a smooth easy process. I would recommend your company and products to anyone. Thanks a bunch.

I received the pipes this morning around 9:45 and had them installed by 11am. They sound great and if it was not for the snow on the roads I would be out on it now. I have steered a lot of people to your web site and they were waiting to hear these pipes as bad as I was. I even left some noisey phone messages to a few. Thanks
I got my new slip-ons the other day for my 2010 FXSTC. Easy install, loved them from the fist minute I opened the box. Started the bike and my wife said, "Loud, ain't they?" So I installed the mid rumble baffles I ordered too, much better...for her anyway. Absolutely love the fact it takes about 2 minutes to put the baffles in or take them out if riding alone. I've been a jet engine mechanic for over 30 years. I know noise, and these things rock!!
Your customer service is second to none. I appreciate the phone calls and the advice you gave me. You have a very satisfied customer.
