Works well for a Subaru, but the nuts are a bit undersized.
This works well for a Subaru's exhaust, but the nuts are a bit undersized. Not sure why they did that... But still big enough that it holds everything together. Much cheaper than OEM, and gets the job done. Thanks Dorman!

Worked for my exhaust install
Used three of these sets to replace my entire lower exhaust system on my 2004 Toyota Camry . I hope they last a while and don’t rust as bad as the old ones did.

Exhaust bolt kit used to connect tailpipe & muffler together
Bolts were long enough to connect my new tail pipe to the muffler on my Honda Element. Cleared both flanges with the gasket installed and was the perfect length to secure everything together.

It said it was not compatible with my 08’ Civic Si. The car came with an aftermarket exhaust system. As you can see on the picture, it’s perfect.
