Product is very well manufactured, solid, perfect fit and exceptional sound and looks. I have one major concern. My wife rides on the back pillion seat and the stock exhaust offered a extended heat shield protecting her legs from burning steel. The Moriwaki offers a slotted, small, bolt on heat shield between the exhaust pipe and muffler. When my wife sits on the bike, her legs are much farther forward than the heat shield and DO NOT come close to touching the heat protection plate. She is 5'2". JUST DOES NOT MAKE SENSE TO ME. I feel ripped off because I choose this exhaust system over a much less expensive Diablo exhaust just because the Diablo did not offer a heat shield. I would like webike to assist me in correcting this matter since I think for 22,000 baht I should have a exhaust system that a passenger does not have to burn her legs to have a ride. Contact Motiwaki engineering and solve this issue for me please.
