hi everyone. i acquired my 2004 raptor 660 back in 2024. The only problem im having is that it came with a curtis Sparks x6 header and an OEM muffler that I believe they cut off the old pipe of the sparks muffler and welded it onto the OEM one. It is jetted for the sparks performance header and runs amazing but I would like to find a sparks racimg muffler if anyone has one for under 100.

alternatively. I purchased a pre-owned original Model FMF powercore mucfler and power bomb header. Only problem is

1. The muffler doesn’t have a replaceable spark arrestor screen and is torn.

2. the header tubes diameter is smaller then the sparks so the jetting is off and I don’t want to change it.

3. I’d like to use the FMF muffler on the sparks header but it’s extremely short.


can anyone let me know if they have a sparks muffler they’d be willing to let go for 100 or less?


or can someone share with me how I could use the FMF on the sparks header? Thank!
