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.

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.

Twin Slash Slip-On Mufflers
As with all muffler changes, they go on a lot easier than they come off! Looks and fits great on my 2016 Slim S and when paired with the Fuelpak FP3 from Vance and Hines, runs like a champ.

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 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.

Do I need to re map 2017 harley deluxe after installing?
Michael F on Jun 18, 2017
BEST ANSWER: You should always remap after changing anything with your exhaust that increases exhaust flow. If you don't remap you can make a too lean condition due to exhaust scavenging and cause long term damage to the engine.
