FMF HEX Q4 Quiet Core Spark Arrestor Insert
John Don't. "It barely fit and didn't lower the noise at all. Quiet core? Now I'm having trouble returning it."See all reviews for this product

FMF HEX Q4 Quiet Core Spark Arrestor Insert
Derek - Michigan Got stuck in my PC4 Hex "I waited for almost 4 months to get this quiet insert. It finally came back in stock. When I went to instal it, The insert would slip half way in and get stuck. A tap with my palm was enough to wedge it in there so I couldn’t fully instal it or remove it... I ended up riding with it for about an hour. It IS a lot quieter than the bare PC4 Hex but either my pipe ID is under sized or this insert is oversized. For that, I give 2 stars as this insert was the reason I bought the PC4 in the first place. I even called FMF before I bought the insert to ensure I was ordering the right part number."See all reviews for this product
