Neal,
How much noise do you want to hear? Imperial owners love to keep their cars
quiet, but on other vehicles I own I have converted from single exhaust with
cats & muffler to dual with dual cats & NO MUFFLERS. The cats keep it fairly
quiet except at full throttle where it gets a little bit louder. With a carb
(non-EFI like the Imp's) you shouldn't have any adverse effects.
Just a thought. I did it on my 79 Trans Am, 88 Dodge/Shelby CSX and both
worked out great. (CSX was a single exhaust, but still lost the cat).
