Just make sure your exhaust issue is not a gateway to other possible violations.

This post makes me wonder if a muffler needs some exit back pressure to be most effective in quieting the exhaust. Additionally, if one wanted the loudest exhaust possible, exiting underneath the car midway, likely provides the best acoustic coupling, ie loudest, kinda like how some small consumer home sub woofers are designed, with woofers facing the floor. twocents

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
