Love them

October 1, 2013

I own a body shop and I'm very picky about what products I purchase, I review them and ask my fellow Harley friends.. These pipes were on my neighbors 2011 Roadglide, I just loved the way they sounded when he would start up his bike. I own a 2011 Streetglide with stock pipes, which were horrible to say the least! I bought a Harley, not a honda! I wanted the real sound of a Harley... These pipes were the perfect solution.. They turned my bike into what a Harley should sound like.. Great price, shipping was quick, and they took 15 minutes to install and fit perfect..fell in love with my bike all over again!

I would recommend this item to a friend.

Good Value

September 21, 2012

Just received my Python Scalloped mufflers for my 2010 Ultra. Took about 30 minutes to install. Only was able to go for about a 5 mile ride, but I already like the sound. Not too loud. What I like is you can purchase optional baffles to customize the sound you want. Very nice looking, will see how they hold up. As usual Dennis Kirk was a pleasure to do business with. Easy to order, a good price and they arrived exactly when they said they would. All in all a great buying experience...

I would recommend this item to a friend.

Nice mufflers.

July 13, 2012

Bought these a few weeks ago. Very easy to install. At idle, they have a low rumble, but once you get through the gears they sound even better!

Great buy and nice throaty sound

November 30, 2011

Put these on my 2011 FLHR as replacements/upgrade to stock pipes. Complete de-install of stock pipes and install of new ones took me 30 mins.

python III review

March 21, 2011

Great quality slip-on mufflers. The fit was perfect and had good heavy duty clamps with larger diameter bolts than stock. Also had a deeper tone than the scream'in eagle slip-ons I had on previously. The cost was almost $100 cheaper than what the Harley shop had to offer. All in all they were an excellant purchase in my opinion.

I would recommend this item to a friend.
