5 Star


These are easy to put on, and the sound is unbelievable, not extra load, just that powerhouse sound. Great, I love them. They look great on too. Very satisfied, recommended! Western Kansas


ideal for those who don't want loud yet want to let people that they have arrived


Not as loud as some other slip-ons on the market, but they still make a great Harley sound with back-fires and all the things you expect from a high performance muffler. The good news is at highway speeds they aren't going to make you deaf so if you are on a long trip listening to music or trying to listen to a GPS.. it's a better long haul experience.. performance improvement was immediately noticeable, but now with a new air filter and new pipes, i'm running lean and will need to purchase a tuner so i'm not ruining my valves.


Put these pipes on my wife 2010 Heritage Classic. Simple to install, pipes sound awesome.Very Happy .


4 Star


Great looking muffler. Kinda deep rumble, not quite as loud as I would like !!! Can hear radio perfectly. Better than stock and good deal for $300 bucks!


Good looking muffler's not quit as loud as I would like (4 star's) wife love's the sound !!!!! much better then STOCK!


So far I have not put too many on them, they sound good.


Great quality & finish. Took 25 minutes to install. Nice sound, but kind of quiet with stock catalytic headpipe. Much louder without the cat, but I really like them on 2012 FLHTK.

Blueing is caused by tuning characteristics, cam timing, carburetor jetting, overheating, etc. and is not caused by defective manufacturing. No refunds on exhaust pipes once motorcycle is started unless there’s a manufacturer’s defect.
