Why You Need an Exhaust Adapter
I found that an exhaust adapter is essential when connecting different pipe sizes. In my case, I needed to connect a 3-inch exhaust system to a 2.5-inch pipe. Without the right adapter, I would have faced issues like leaks, reduced performance, or even damage to the exhaust system.
