Henry, Finished the dual exhaust on my 292. I had long tube headers into stock exhaust. I now have the headers (Pacers??) into dual 2.5 pipe to a pair of Dynomax Super Turbos. Definite difference even with the 1bbl. It feels like I've gain torque over the entire rpm range, and more responsive to the throttle. I've been running the 1bbl lean on the rebuilt 292, so this week I'll step the jet up.
