It fits HiSUN 500 2011-2018ish. WE ARE ONE OF THE LARGEST HiSUN PART CENTERS IN THE UNITED STATES. This has O-2 sensor hole for EFI. "Bucket Seat" type UTV's. (Header Pipe). Both Exhaust Gaskets Included, not shown .
I believe this item is overpriced but the machine had to be repaired. Next time I will just reweld the broken weld and go from there.The pipe appears to be very well made and a change in where the weld is at might make it less likely to crack again.
The length was about 1" too short. I compared it to the original that I removed. I had a very difficult time installing it because it is shorter. I had to loosen other exhaust pieces to get them to mate up and now the muffler section cannot be secured the way that it was.
