I own a 2012 triumph TB LT and replaced the stock mufflers to the Vance and Hines mufflers sold at J&P cycles. Wow!!! It took me less than 2 hours to install them leisurely and fitted perfect!!! I was eager to start her up.....and a deep throaty growl came out of the pipes!! I'm so happy and satisfied with the workmanship and simple and easy to follow installation steps; simple enough for an intermediate student!!!!


Great Sound! Just what I wanted: Louder than stock (a throaty rumble) without being obnoxious. There is very limited clearance, so installation took awhile longer than expected, but that's on Indian, eH? Fit & Finish is 1st Class.


Great product, fair price, quick delivery.


They fit my 2016 Harley Davidson Free Wheeler and they sound great. Thanks to UTube, fellow rider for help on pulling the backend off that was a chore. You can't go wrong with Vance and Hines

Mufflers are typically well made items from Vance & Hines. Slight difficulty getting the bolts, that mount the cans to the supports, to engage the nuts holding the muffler brackets.


Easy to install. Great sound.

I received the mufflers exactly the day that I was told they would arrive, It took me about an hour and a half to install them because I needed the right tools. It was real easy after that. They look great on my bike and the sound is tremendous! I'm also real impressed with the performance over the stock pipes! :)


Really love this exhaust sounds great and easy to install


I put these pipes on my Kawasaki 1700. It took me about 1 hour to install them and I absolutely love the deep throat growl and the performance is noticeable.

Important Product Notes

Note: Please see U.S. EPA and your respective state and local regulations to confirm noise and emission compliance.

Important Exhaust Notes:

• Note: With any new exhaust, we recommend changes to carburetor jetting or use of an aftermarket fuel injection control module.

• There is no warranty on exhaust pipes and mufflers with regard to any discoloration. 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.

• Flanges and retaining rings are not included with most aftermarket exhaust for 1984-2013 Evolution and Twin Cam models. Re-use your existing hardware, or purchase replacement hardware.
