ok on the turbo with the v-band clamp style what size do you use? measured mine from lip to lip and it said 3.5 but not seeing any one running that they are all 4 inch? what one do i need to order3.5 or 4?
ok i have a master power 62-1 turbo and the out let side that hooks to the down pipe that needs the v-band clamp on it measured 3.5 inches from lip to lip do i need to buy a 3.5 inch clamp or a 4inch clamp? because all the turbo cars i see have a 4 rarely see one with a 3 so didnt know if i need to over size a little or just stick to 3.5
