Dougs to summit exhaust

Just plan for a couple of test fits. I used the included exhaust clamps for doing all of my test fitting and trimming, but I welded all the joints except at the mufflers after I was done. Too many clamps/chances for exhaust leaks otherwise. I'm sure it would work ok for awhile with just the clamps, but I drive a lot and my car sits pretty low, so I wanted the durability.

Here's a clip of my Duster with the 2.5" exhaust, Doug's headers, and welded ultra-flo's. It's got a ~400 hp 1968 340 though, .060" over, KB 243 hyper pistons, Lunati 60404 cam, duration 276/ 284, Lift .513/ .533. Compression ~9.8:1, 308 heads ported and flowing 264 cfm @ .500".
