I don't know how it is possible to buy a nearly 10 years old muffler with only minor scratches. When I unpacked the muffler I was ready for disappointment but it was even better in real life than the pictures. No dents and no excessive noise. I am a happy camper.
Works great, cheaper than aftermarket performance exhaust and works just as well.
Put this sxf muffler on my 450 XC-W. It is slightly quieter than the FMF 4.1
