torq monsters daytona
I wish I could say the same,when I first installed them we went to the keys it was almost 600 miles, my brother who also has a gl1800 went with us .We both got about 220 miles before needing gas. we stayed about the same thru the trip ,but during the next two weeks I notice I was only getting about 150 to 165 out of a tank of gas ,so I ask my brother if he wanted them for his bike he told me sure .well about two months he had them on his bike and he remove them for the stock muffler .I do say they sounded great but it was not worth the sacrifice .The guy at the Honda service told me that Honda uses an altitude meter to adjust the air fuel mixture on the gl1800 so that the bike will run the same if it is in the mountains or the keys it should get the same fuel mileage ,he said maybe those pipes are changing something any way i have a set of 490.dollar torq monsters just sitting here
