        Rated 5 out of 5 by from Great sound, love hearing it rev out Great sound compared to stock, sounds more poppy. As far as performance goes I did not notice a major difference. Much smaller and lighter than stock really happy with the overall look. Would recommend.

        Will this fit my 2019 KTM 300 XC-W tpi ? Is there a noticeable sound difference if so? 

        Asked by: JeffRK
        Yes, if you enter the year, make and model of your vehicle on the product page, you will see that this item is a "Guaranteed Fit" for your bike. Please note: If you have a Pro Circuit R-304 Silencer, you must run a Pro Circuit Platinum or Works Pipe.

        Will this fit my Dr-Z125L 2018 I ride every other day and keep it clean

        Asked by: Lime
        No it will not. This silencer is only made to fit 2 stroke race bikes. You have a 4 stroke trail bike so the R304 is the wrong silencer.
