Just my opinion, but what you describe does not sound "good", at least not to me.

If you want something reasonably noisy when you want, but still pleasant sounding if you drive careful then Flowmaster mufflers would be a good choice.

Had a single one (two into one) put on a 78 IHC 304 V8, sounded pretty good I thought.

I've had louder exhaust, it's fun for a while, but people start to complain...
Flowmasters would be my choice.
