Pro Circuit Spark Arrestor Screen Pro Circuit Spark Arrestor Screen Dirtfarmer - Round Hill, VA 20141, USA Works for a stock 2003 TTR-125 muffler "My sons bike didn’t have a spark arrestor so we easily modified this to work on his stock muffler. We thought we should have one for trail riding. It does give make his bike a little louder and throaty sounding since the opening is almost a full 1” compared to the washer at 1/2”. Similar to when you simply take the washer off. He loves it. When trail riding though we just put the end muffler washer over it to quite it down. We bought the smaller duals mini. The screen that goes into the bike is 4” total length and a little 1” at the widest width. The end cap is @2 3/8”."
