A great sound
I bought and installed the Double Nasty Slip-Ons. They are very easy to install and look good. The sound is great. It has a nice rumble when at idle and growls when accelerating and opened up. They are not too loud and I have had compliments on the nice sound.

Absolutely great
Bought about a month ago. Took 20 minutes to install. Look great and sounded alright. A week later I pulled the baffles out and took off the fibreglass wrapping. Perfect sound not to loud not to soft nice deep sound. Would definitely recommend.

NOW it sounds like a real bike!
I got these pipes on spec but am pleased with the performance boost and sound, although they are a bit to loud. The rap when not under load but now I can hear what my bike is doing as before I could not tell given I have no tach. Thanks FortNine.

Excellent upgrade!!!
Très bon slip-on... S'installe facilement. Côté sonore, c'est incroyable, même les HD se tournent la tête et se demande qu'est-ce que c'est. Donne un peu plus de torque mais pour une performance optimale, les carburateurs doivent être ajustés.

Save your money!
I bought these pipes in 2018 for a winter install, after the first year, the cheap, thin chrome finish peeled and pitted with rust, the tips did as well. One year warranty from date of purchase, they wouldn’t stand behind their product.

Nice pipes
I recently purchased this bike and I wanted to change the slip-ons because I personally like a little bit of a noisier bike.... These slip-ons were ready enough to install but when all is said and done, I would have liked them to be a bit noisier.....

Questions
Do the carbs need any adjustment or jetting work done after installing these pipes? I'm riding a 04 royal star venture.
I have them on a 07 Royal Star and other than sound and a slight performance increase, no changes/adjustments are noticed or needed.
