Like the title says, works great for its intended use…gives a nice range of sizes.

The adapter worked perfectly on my CB350. I only used two of the sleeves to go from a 1 3/8 to a 1 1/2. Not sure it's a complete seal where no exhaust will escape but it is firmly mountedon now. I plan to test the leak theory later and add an update.

Part is the right size needed. Very disappointed that it spent a week in Georgia. Would have returned for that fact alone if I didn't need it.
