On that last trip to the river months ago, the truck developed an exhaust leak at the driver side collector. It sounded awful. I finally had time last week to take it apart, but the gasket is not a standard part. The manifolds are Summit Racing 2.5", and the gasket was only available in a $50 kit with all the bolts and other gaskets.

I bought $10 Mr Gasket 2.5" collector gaskets and enlarged the center hole with a rotary tool to the correct size (about 2.75").

Fixed! The truck sounds healthy again.
