Python Mufflers
Excellent sound. Their size looks better on the bike than stock HD mufflers. My dyno guy says they out-perform most slip-ons he's seen. They'd be perfect if they didn't have logos.

Look awesome and sound awesome!
Could not be happier with these. Put them on my wifes 2010 Street Bob. They look awesome! For the people out there who cant afford to go to a full system, get these pythons. They look amazing, and sound even better! They have a good loud crisp sound, ya know, like a Harley is supposed to sound. I would recommend these to anyone. Easy install, great price, look great, and sound great, cant beat that period.

Great Pipes, Great Value
These slip-on are some of the best I have ever heard. They have a nice low tone and are not obnoxious. They are very well made and after a week of use, no bluing. The fitament is great. With the factory head pipes and heat shields attached, it looks like drag pipes. Very smooth transition between shields and mufflers. Would recommend them to anyone looking to upgrade the factory exhaust.

AWESOME SOUND
I purchased a set of these slip-ons for my 2008 Super-Glide and couldn't have made a better choice. The sound was frickin AWESOME !!! Very nice deep meaty sound like a Harley should sound. EVERYONE who's heard them since I had them installed was VERY impressed by the HUGE difference from the Screamin' Eagles I had on before. Not even CLOSE !! These slip-ons blow the others away by far. Would definitely recommend these to anyone who's thinking of moving up to a more beefy sound. I love seeing peoples heads turn when they hear that thunderous sound approaching. Great purchase. Definitely buy a set and you won't be disappointed.

Perfect
After shopping around for months, I finally decided to get these slip ons for my street bob. I ordered from Dennis Kirk and they came very quick. After the same reported problems of removing the old pipes, I got these bad boys installed and couldnt be happier. Deep tone, no "tinny sound", and amazing look. They are great for cruising with no drone, but crack the throttle and these beasts wake right up. Not a better slip on out there for your dollar.

Great Purchase for HD Softail Deluxe
The Python slash cut slip on mufflers were a perfect fit for my 2008 HD Softail Deluxe. Installation was a breeze. The stock exhaust was much more difficult to remove. The mufflers sound great especially the deep tone in 6th gear. They are not too loud but do make a HD sound like it is suppose to sound minus the stock mufflers. Great price for a well made set of mufflers that perform well.

Completely Satisfied
First of all living in Alaska shipping can be a hassle. I ordered these pipes and they were shipped out right away ups ground and arrived in 5 days and the shipping charge was very resonable. Now the pipes.I had the dealer install them, they had the olds ones off,new ones installed and recalibrated in less than 30 minutes. the look and fit is awsome. the sound is even better!very happy with these Python pipes.

great pipes
Recieved order quickly. Slip on mufflers were easy to install. Took maybe 30 or 40 minutes total to remove old pipes and install the Python pipes. Great sounding pipes. Same sound with slip on pipes. Saved a great deal using the stock header pipes. Great deal from Dennis Kirk.

Do you need to re tune a fuel injection bike with these?

BEST ANSWER: Wish all exhaust changes there is the possibility of having to re-jet or re-map the fuel/air mixture levels. We recommend contacting the manufacturer Tech Support for better information on those needs:
