Well, exhaust sound is a subjective thing, each one has his/her own preference. Personally, I'm one old-timer that loves the sound of a Chevy or GMC 6 rappin' out through the gears. I liked it back in the 50's and I still like it.
I prefer old school when it comes to modifications. Old school (in CA where I grew up) was Fenton's or a split manifold, Smitty glasspacks (still available) and 2" or less piping. The longer the Smitty, the quieter the sound. And no one ran a crossover.
Run the tailpipes all the way out the back. Just my opinion.
