A long time ago I put a pair of Cherry bombs on my 68 Roadrunner. A few days later I took a road trip to TX.
About 200 miles into that trip I wanted those things gone. The drone at highway speeds gave me a perpetual headache.
About 20 miles from home on the return leg a state trooper stopped me and wrote me a ticket for illegal mufflers. Before I could change back to factory mufflers the city police stopped me and also wrote me up. A few days later the factory mufflers were back on the car.
I have no idea how loud your car will be but the converters are the biggest restriction in the exhaust system of any car and especially so after some age and miles. The substrate in the converter starts getting caked up with hard carbon and worsens the restriction part of it.
I’ve driven a few vehicles sans mufflers with converters in place and they were not that loud at all. Friend of mine has a 3 wheeler with a 350 Chevy motor and long tube headers. No mufflers, no exhaust pipes, and just a few puny baffles in place. I’ve ridden it and it’s actually no louder than my son’s 96 stock Camaro.
