Review on 🏃 Enhanced Performance: Walker (33975) 2-1/4" Aluminized Mega Clamp - Unleash the Power! by Dave Goodman

This joint was perfect for my application ('03 Pontiac Vibe). I had an exhaust pipe ripped off the cat outlet (clean crack at factory weld). The exhaust outlet was 2 1/4" OD and the catalytic converter outlet flange was slightly larger, more like 2 3/8". This clamp fits snugly on either surface. Before putting the collar on I applied a seam sealer around the seam. When I tightened the clamp the sealant was leaking around both ends so I'm pretty sure I have a good airtight seal. Installation was very easy. The part bends easily enough that you can fit it over an existing pipe - no problem. Aligning the screws and tightening was easy. (Others have complained about the difficulty, but I have to wonder if they got the connection size wrong.) The quality seems pretty good - we'll see what happens over time.
