yes i know...becoming old and farty. recently acquired 94 rx diesel turbo with 3"system and muffler which looks like an oversized hot dog from the good ole days. initially the noise wasnt an issue but a trip away fully loaded and the drone gave me a headache after 3 hours.
a mate had similar issue with his td42 .he installed a new muffler.got under and had a look and it said "super cat" if that means anything to anyone.he said it has a wave type baffle so it is still almost straight thru.
im also looking at sound deadening the bus as well.so couple of questions

do they make a quieter muffler for the 3" system and would i have to get turbo timing (or whatever the magic is) redone as well.

what type of sound deadening do you use

thanks .ned
