Great quality item

Great quality and a great price! All good!

Exactly what I needed—solid fit and finish
Size: OD 3.5" to OD 4"
Exactly what I needed—solid fit and finish Needed a 3.5” to 4” adapter for my custom exhaust setup, and this pair worked out perfectly. The 304 stainless steel is high quality—nice polish, decent thickness, and no rough edges. Both pieces slid on with minimal effort but still felt snug enough to clamp or weld without any struggle. I especially liked that they’re a full 4 inches long, so there’s plenty of overlap to get a secure connection. Zero leaks after install, and they look good enough to leave exposed if needed. No weird flaring or inconsistencies between the two. If you’re trying to transition between sizes cleanly in your system, these are a great option. Would definitely grab again for future projects. ... show more

Perfect for custom project needs
Size: ID 2.5" to ID 3"
Used these to get some 3” inlet/outlet universal high flow cats welded up, for my long tube headers (has 3” inch - 3” OD collectors) and stock 2.5” inch (2.5” OD) diameter catback exhaust. Factory exhaust clamps were a OD to OD exhaust diameter connection, so I kept those “butt joint” style exhaust clamps. Not the best thing if you have gaps in between the exhaust pipe length, but a small gap can still be saved… ... show more
