I just installed the DRD complete titanium/carbonfiber exhaust with the lowered radiators. I was wondering I noticed hot much hotter it seemed coming out at the head as it makes the bend you know. Does anyone know if this will make much of a difference since my waterpump and hoses are right there? I have a 07 YZ450F by the way. Also do you think it would help to either put the boyesen waterpump cover and shaft on or put the CV4 rdiator hoses on? If need be I will just get both.
