V&H high output

By   on  Verified Purchaser

Sound is perfect for my 110 motor


Great slip-ons with nice deep rumble

By   on  Verified Purchaser

Generally do not write reviews, but had to here. After spending way more time than I should have looking at slip-on mufflers, I settled on the V&H Hi-Output and could not be happier with my choice. Exhaust went on my 2014 Ultra Rushmore w/o any surprises. Overall fit and finish of the slip-ons was excellent. The sound of these is like a V-8 muscle car with a nice deep rumble, not just loud and obnoxious. Next up, a tune.


Best of the best

By   on  Verified Purchaser

This muffler sound is exactly what I was looking for! Deep low rumble. My 2016 Harley 750 street is a beast now. Absolutely love it!


Great

Great product


New Pipe

By   on  Verified Purchaser

I did a lot of searching for the pipe I needed. Quality was great and my bike sounds awesome.


V and H high output

By   on  Verified Purchaser

The slipons themselves however, are a bit quiet for my taste.

Bought them twice!

By   on  Verified Purchaser

I purchased these to replace the same mufflers from 2011. V&H changed them a little. No longer has a heat shield over the slip on section. Changes the look. But they still sound great.

Questions & Answers


Will this fit my 2025 Road Glide

Absolutely! Just choose the 2025 Harley Davidson FLTRX Road Glide from our fit guide and you'll be all set.

By Tom

Will these fit the 2022 Fat Bob 114?

After checking with Vance & Hines, the 2022 Fat Bob 114 would use the same slip-on as the 2021 Fat Bob.

By Andy

Will they fit a 2017 street guild special

Yes, you can choose that 2017 FLHXS Street Glide Special from the list of models these slip-ons fit.

By Andy

Do you have to remap with these slip on's

Regarding your question on our website about the Vance & Hines Hi-Output Dual Slip-On Exhaust; "Do you have to remap with these slip on's" If you're only installing the slip-ons and you do not have an aftermarket air cleaner on your machine, then there's usually no need to adjust fuel delivery. The OEM ECU can typically handle the changes in fuel requirements when going from a completely stock configuration to slip-on mufflers only. If you go beyond that level of tuning, then adjusting fuel delivery is a must with a device such as a Vance & Hines FP3 fuel controller or Cobra Fi2000R fuel tuner. In rare cases, a bike with only slip-ons added may require fuel tuning, but that only comes up if you ride at high altitudes (eg. above 4,000 feet) and/or the fuel you're using isn't of the greatest quality. Otherwise, you shouldn't need to do much of anything but add these mufflers to your bike and hit the road!
