This insert core definitely makes a noticeable difference on my yz426f, easily makes it legal to ride in range of the national forest regulations. This fits on the stock silencer but you need the DR. D end cap to make it work completely. Also it is removable. -James

Great Product
Only reason i wouldnt recomend it is because i race motocross and quite to me is garbage. my Dr.D sounds fine the way it is and its perfect for racing. not to sure if the power loss of the quite is noticable but if you are restricted by sound pick these up and you will have no problems any more. doesnt kill the pipes sound it just tones it down, will still have the nice Dr.D rumble but non the less is a great product

Dubach Racing - DR.D - Does not list the dB on their inserts, claiming it differs from bike to bike. they ask all inquires to be made to their Technical Team, http://www.dubachracing.com/contact.html.

With this Dr. D arrestor...?
Will it mount up to my stock 2007 YZ250F exhaust?

These Spark Arrestors only fit DR.D D-shape exhaust systems. This will not adapt to a stock exhaust.
