The FMF Ti4 Spark Arrestor End Cap is a replacement endcap for the STOCK non-spark arrested endcap on the FMF Ti4 muffler. If you do not want to run the spark arrestor, than reinstall the stock endcap.
Unfortunately, this will not fit the stock exhaust, it will only fit the FMF TI4 muffler. The stock exhaust should already be spark arrested on your 2007 Arctic Cat 500 Automatic. If you need replacement parts for this specific model, please contact an authorized Arctic Cat dealer.

What is the outside diameter of this end cap? What are the mounting hole spacing?
I know it's for fmf pipe, just want to know if it will work for my pipe. The manufacturer doesn't make a spark arrestor tip for it.

We were able to get an answer from FMF Racing directly for you and here is what they came up with:
"The end cap is round measuring 3-3/4 inches across and the outlet is 2 inches across. The spacing between the holes is 2-3/4 inches from center of the hole.
