Dave,
Eliminating the muffler is only going to increase exhaust noise. It's more
likely that you are working the 4 banger hard to get the truck over 60 and what
your are hearing is intake and/or exhaust resonance thru the sheet metal of the
cab. Changing to a less restrictive muffler or wrapping the pipes with one of
those muffler bandages may move the resonance to another frequency that does not
corrospond to your highway crusing speed.
