The nuts and bolts on the existing exhaust flange for my Jeep TJ rotted away. I had to cut the flanges apart. Thankfully this worked like a charm to reconnect everything. With the right gaskets, no leaks, nice and quite again. I'll buy a few more to keep in the parts bin. Read more

Works great! The flange on a new catalytic converter was flimsy, weak and bent while attaching. I removed it and attached this flange and saved my purchase. I highly recommend this product. Read more
It pains me to write a negative review on this product, because several of their other products are usually a little better quality than the competition. However, that was not the case with these split flanges. They're not zinc coated, only spray painted silver. The bolts are too short (see pic). They should be 2" inches long instead of 1.75". Had to file off part of the weld (see pic), so it would close completely. Also, I can't speak for the other sizes, but the 3" exhaust flange is so tight on my pipes that it cannot be rotated...even when everything is only finger tight (see pic). Had to do a lot of grinding and filing in order for it to fit a little better around the pipes. I also had to enlarge the tubing where the bolts that hold the flange together because they were misaligned when welded, making it extremely difficult to get the bolt completely installed. Needless to say, I was disappointed with these flanges, especially considering they were a few dollars more than the competition. Read more



used for a Subaru Outback 2012 to connect the middle section of exhaust pipe with muffler. It was perfect. Read more
I clicked on this one accidentally which was next to the kit I needed and both Amazon and the manufacturer are giving me the run around on exchanging it. Read more
These flanges worked perfectly for my exhaust repair. The fit was spot on, and the carbon steel feels durable. Installation was straightforward, and they sealed the connection well. A solid, reliable replacement kit. Read more
