FMF Q4 Spark Arrestor Slip-On Exhaust

JBB Concepts - New Kensington, PA
5 out of 5 stars
Your wr250r needs this! "100% satisfied with the Q4 on my 2020 wr250r! Paired with a megabomb header and the bike sounds like it should instead of a sewing machine! Only minor issue was needing a longer bolt for mount near passenger peg. Well worth price otherwise"
