I got a 2009 Crf150r about half a year ago and I love it however it’s real loud, I like it loud, but I’m sure the neighbors don’t.
Anyone know any sort of way to quiet it down with out completely ruining it, I know there was things such as Db dawgs but I thing they stoped making it, thanks

Hello and welcome to the site.
There are many manufactures that make quiet type mufflers. FMF, White Brothers, LEXX and most will have a spark arrestor option that also quiets the exhaust note. I ma not sure of who makes the mufflers for the CRF150R but I bet they all probably do.
Another option is to go back to OEM stock muffler which are probably the quietest of any muffler you can put on.
You did not state rather you have a stock or stock modified or aftermarket muffler on the bike.
Just so you are aware - Jetting changes will be required if you do a major change from what you have.

Thanks, I have a stock pipe, maybe I should just repack it?

If you have a stock unmodified muffler you would be wasting money trying to buy a quieter muffler. If it is able to be repacked then yes that is a good option.
Your neighbors will like you.
