Installed on 2010 HD Heritage
These are nice slip on mufflers. I would recommend them to someone who wants some sound but not worried about added performance. The most difficult part was removing the stock pipes from the bike. Mine were stubborn but once off, not too bad on the install. The use of the existing HD muffler clamps also a bit tricky, the VH slip ons are just a bit larger in diameter so you have to stretch the clamps them bend them back to fit. I would recommend a large set of pliers for this. No mapping needed if only these are added. Enjoy!

Great Slip-ons
Installed on a 2010 Fat Boy Lo. HUGE improvement in looks and sound over the stock mufflers. Difficult to install though. The stock mufflers have threads tapped so you just screw the bolts in and out. These aren't tapped so you must fit washers and nuts on the bolts, in the smallest and most awkward spaces imaginable. Then fit a wrench on the nuts in the smallest and most awkward spaces imaginable. Other than the difficult installation, LOVE them. Would buy again.

Sounds great
These mufflers were very easy to install and look great.
They let people know you are coming but not from a
mile away. They sound really good.

Great for Slip-Ons
I mounted up these pipes on a Softail Heritage and a Deluxe. Much easier on the Heritage! Took about 1.5 hours on the Heritage and 2.0 hours on the Deluxe. Everything fit as advertised although the mounting bolts for the Deluxe were too short if you've installed the optional saddle bags.

Sound is very different between the two bikes even though the mufflers are identical. The shotgun setup on the Deluxe gave it about 2 more HP both stock and with the new pipes over the Heritage. Still can't keep up with the wife!

Overall these slip-ons are far superior to HDs Screaming Eagle slip-ons and at DK they are about $100 less. I also installed Arlin Ness Big Sucker aircleaner kits at the same time. The HD ECM calibration for their setup worked just fine and sure saves a lot of time, money, and hassle over an aftermarket programmer/tuner.

Great Purchase
V&H Mufflers have a nice look, great sound and simple installation.

DK price was very competitive, online ordering was simple and the mufflers were delivered in a week.

Great sound
I love the sound. It took about two hours to install. The brackets on the slip ons need to have the nuts tack welded on the brackets, It was frustrating trying to get them started. I finally ground down a socket end wrench to hold the nuts. That was my only problem.

Well worth the money !!!
Installed on my 07 FLHRC it only took about 30 min to remove old and install new. The sound is great ! To me the sound is about twice as loud as the stock mufflers. not ear bleeding loud but loud.

After installing these mufflers is fuel mapping needed?
A shopper on Apr 3, 2017
BEST ANSWER: Whenever changing exhaust, due to back pressure and air mixture changes, it may require the use of re-jetting or re-mapping products
