RE: Exhaust pipe for Baja, not loud
Samba makes some very nice pipes, they have a good tone and are quieter than most. FG Supply has a Samba for the HPI on sale right now for $135, which is an excellent price for a Samba. I haven't used this particular pipe but I have used Samba pipes on my FG's and they produce nice power without the ear piercing sound of some pipes.
