Nice upgrade!

Just installed on my 23 FXLRST/10-2-24. Had a hand made like everyone is doing. Wanted a long tube header pipe, choices are very limited. This pipe worked perfectly, sound great as well.

Pipe looks great and sounds great. Make sure you get a tune if you are going from stock exhaust.

Do I need a to buy a muffler braket

So long as you have the OEM exhaust on your machine, or have all of its components on hand if you're already removed it, no - there's no need to buy any additional brackets to fit this exhaust to any bike you select from our fit guide.
