Rated 4.9 out of 5 by 7 reviewers.
Rated 5 out of 5 by Above my expectations I completed my stage 1 upgrade with these slip-ons, SE air and the Harley Stage 1 download. HP for the $ this seems to be the best option if you don't plan to go to Stage 2. This setup runs ~$450 less than getting a tuner and dyno yet seems to yield about 90% of the benefits. If you plan on Stage 2 or higher in the future get a tuner. The only downside to this whole situation for myself is that the setup is legal and Harley should put it on the bikes to start with. Overall I'm very pleased with the results. July 20, 2015
Rated 5 out of 5 by Nice sound and increase in performance! Fitted these up to my wife's '13 72 Sporty - pretty easy but you do need to loosen the headers - not a big deal. Sound great - not too loud - but louder than the SE slip-ons on my Wide Glide!! Wife says nice increase in power - better for overtaking. Has even improved the range! And if you don't mess with the air-cleaner, you won't need to recalibrate ECM! Has her grinning anyway. Happy wife = happy life! ;) July 10, 2014
Rated 4 out of 5 by Performance is excellent, instructions could be better I purchased these mufflers and they sound/ perform great; not too loud, low aggressive rumble, and plenty of torque. However, the installation instructions could give you more guidance on how to remove the stock mufflers and install the new SEII mufflers. I had to completely remove the heat shields on the header pipes, loosen the support bracket, and use WD-40 to loosen the stock mufflers. There was no mention of any of those steps in the provided instructions. Any case, I am satisfied and really enjoying my bike. October 25, 2013
Rated 5 out of 5 by Dual Shorty Exhaust Power Gain I installed these slip-on because Motorcycle USA said they increased horsepower and torque by 7. They actually do, maybe even more. The sound is great without being annoying. I also did the Stage 1 Intake and had dealer to ECM download. What an improvement over stock. Not only increased power, but runs much cooler and awesome top end. October 10, 2013

I was thinking about adding these pipes and a K&N air filter. Will I need to re calibrate the ecm, and second part how would this effect performance?

Answer: 
Upgrading your mufflers and adding an Air Cleaner will definitely increase performance on your XL. You will have to have your dealer do a re-cal once everything has been installed.

Answer: 
Hi RedneckDAE,

If you are referring to P/N 65927-00, which is Item #1 on the last page of the Sportster Accessory Slip-On Muffler Kit Instruction Sheet, you can purchase the gasket at your local dealership.

Thank you for your question.

Answer: 
Hello Bill69,

The recommended fitment only goes until 2013. They may physically fit, but may not pass emissions or for other reasons. Therefore, we do not recommend installing them on a 2014.

Thank you!
