I am currently rebuilding the 318 for my '70 Duster and I don't know if I'll have enough money for a new exhaust system when I put the engine back in, and I definitely don't want to hook back up the stock system (WAYYY too small and quiet). So I was thinking, how would it work if I got two lengths of flex exhaust hose and just rigged them up from my manifolds to a side exit? I know it would be loud as HELL (which I want, for a while at least) and wouldn't flow nearly as well as a good dual exhaust X-pipe system back to the rear bumper, but would still be better than the crappy stock single exhaust. The only thing I'd need to figure out would be how to hook them up reliably to the manifolds and hang them from the chassis.
