Spend money on just the right gearing to get the throttle about 80% open at the engine rpm you are travelling at.
Spend money on higher compression pistons and cylinder heads.All of the above are likely to give
"More Bang for the Buck"
than exhaust system modifications
to improve MPG.

OK so I'd want really high (2.45 ish) gears so I'd need to be deep(er) into the throttle? (around town). Was prob going to do an Atkins build (I have fresh mag neads) depending on how much high CR (318)pistons are & the special cam and right now the car (65 Dart) has a tired/leaky 318 w 273 logs so the ex will need to go and a guy has a new set of the 1&5/8" fenderwells reasonable. I've read/enjoyed his stuff & yes Vizard is no slouch
