Resurrected Junk
One of the problems I knew I would be facing soon would be a replacement of the exhaust system. It looked like it had been stuck together with whatever had been sitting around at the time. The exhaust had been hanging low suspended by coathanger wire. When I put proper clamps and hangers on it, the muffler outlet shifted around.
While carbon monoxide is supposedly odorless and colorless, I was getting headaches while driving but would clear up after staying out of the car for a while. It seemed more than coincidental, so I started driving with the windows down and the vents open. That got me through heating season, but A/C season is up coming.
I look at exhaust improvements as "free" horsepower because opening up the exhaust does not increase fuel consumption such as improvements in intake and valve timing do. After looking at the options and comparing them with my intended use of the car, I decided to install a PowerPipe and increase the diameter of the exhaust to 2¼ inches. My local muffler shop bent an exhaust pipe for me and did the install of everything I brought in. I have a generic offset inlet/outlet "turbo" muffler and a new LH V-8 tail pipe that is all 2¼ inches. The tone is a little deeper under acceleration and actually more quiet under steady state cruise. Sorry no sound clip and no instrumented test. Seat of the Pants observation shows a small improvement in throttle response. The only test I can perform is Top Speed Observed. We'll see about it this weekend.
