Bullet style muffler recommendation (Quiet Please)...yup, getting older lol

Looking for recommendations for my dart, for a small body, bullet type muffler that you actually noticed a difference in after install.

I have 3.5 inch collectors, so ground clearance and real-estate are limited. Currently just have little "anti reversion" chambers bolted direct to the collectors. It's still pretty ridiculous.

Would like to quiet it down enough to drive a few miles down the road without shaking my brains out. (Or getting pulled over immediately)

Sure be nice to check things like brake bias, steering wheel centerline, etc, with more than just the pits at the drag strip at my disposal.

Putting this in the racer section because this is my bracket car, and I don't want a bunch of 2.5 inch Flowmaster recommendations. Thanks all !!!!!!!
