Run with open headers and Holley carb

While I am working on hydraulic T/O bearing problems I started it to hear how it sounds with open headers. I also found out from this how restrictive my exhaust is. The revs were between 6500 and 7000 rpm's. It revs instantly without the exhaust on it. Maybe mt cats got clogged when I had the FI on it--it was running very rich then.

I bought 2 short straight through mufflers to replace them. Maybe these will help quiet the exhaust some.
