How to Measure Your Pipes for Part# 2000, 2001, 2002, QBL2125, QBL1994, QBL1845 Only

1.		When measuring a pipe with a straight cut end, measure across the end of the pipe, outside to outside diameter and inside to inside diameter as shown above in several places, ie 3 o'clock to 9 o'clock and 12 o'clock to 6 o'clock as pipes are not completely round. It is preferable to use a tape measure rather than calipers. Additionally we recommend you measure the outside diameter of your baffle provided you have one.
2.		When measuring a slash cut pipe measure the outside to outside diameter and the inside to inside diameter at the widest point of the slash cut and across the flow of the exhaust as shown in the photo above. We recommend you use a tape measure rather than calipers. Additionally, we recommend you measure the outside diameter of your baffle provided you have one.
