Suggestions for muscle car sound muffler without drone

Drove a ton today and it's so pleasant now. We've got a long slight uphill 45 mph blvd in town that I used to stay in 2nd gear for just to make it more bearable. Quiet as could be today in 3rd. Thanks for all the information buck.

I grew up in Palatine- not too far from you. I took a lot of heat from all the Giants fans at work today wearing my Cubs hat after tarpgate at Wrigley.
