i own a raptor 660 i have a full hmf exhaust pipe on it, what i was wandering and don't laughf at this either, will my stock pipe fit into the hmf header pipe, reason i want to do this is when i go hunting in the woods the old stock pipe is extremely quiter, or will i have to put the complete stock pipe back on it, and if i have to will my jeting be to rich for the stock pipe ,

thanks for any replies in this crazy matter

 

get the quiet core insert.. it should quiet it down quite a bit.. i know that on my warrior it was quieter than stock(especially at idle)
