It's good.

I bought this when I was going to ride up in the mountains and in idaho you are required to have a spark arrestor. I went the week before I had it and put my stock pipe back on. I had a lot of back pressure with it. Man up and grow in the mountains after I got this spark arrestor for my doctor D pipe and love it. I ride from anywhere from 6008 to 10,000 feet and the performance of my bike never changes. Dr. D products are great I love them.

Q: I have a DRD NS-4 exhaust and this spark arrestor will not fit into the end.

I tried to remove what looked like an insert of sorts from the pipe but it would not come out and i didn't want to damage it. This spark arrestor is too big around at the end to slide into my tailpipe. Am I missing something?

A: Make sure to call and verify that the make and model of you bike has the correct diameter of pipe on it to fit this spark arrestor.

A: Dr. D NS-4 Spark Arrestor Kit ONLY works with the DRD brand exhaust systems. They have revised the item from what is pictured to work with the NS-4 systems. They will not work with other mufflers or applications.

A: I do not show any spark arrestor that would work with the stock silencer on your 2007 KTM 300 XC-W. You will more than likely have to purchase a new silencer with a spark arrestor. I would recommend looking at the FMF TurbineCore 2 or the Pro Circuit Type 296 Spark Arrestor

A: No this spark arrestor will not fit the stock exhaust. It only fits the DR.D NS-4 exhausts. For your stock exhaust on the 2011 YZ450f, the only option is the Pro Moto Billet end cap that gives you option to run the included spark arrestor. If you give us a call, we can provide provide pricing and availability of this item for your bike.
