I'm looking for a recommendation on an exhaust solution for my '54 Chevy truck. The previous owner had installed "dual exhaust" by drilling a hole in the exhaust manifold and welding a 2" exhaust pipe in between the number 5 & 6 cylinders. Strangely, the pipe from the "custom" exhaust is run through glass pack muffler. The exhaust pipe running from the stock exhaust manifold location to the rear of the truck has no muffler. The truck's exhaust note sounds like an asthmatic VW beetle, so I'd like to upgrade to more standard dual exhaust system. I'm planning to buy headers for the 235 engine, but I'd appreciate a recommendation for a good muffler/system for the 235 engine. Any thoughts would be appreciated.

Thank you.
