Ideal Street Legal Exhaust

I’ve been contemplating this for awhile and considering it’ll be coming up within 2-3 months, I want you guys opinions.

I’m here in TX, so removing the cats isn’t realistic if I want to pass the emissions test but… a coworker of mine installed a cut-out on his Mercedes CLK 55 AMG, which brings hell itself to your ears out of a V8. What if I installed the JHM exhaust and added in the appropriate exhaust cutoffs to electronically control valve openings? Would it be too loud? Hinder performance? A typical 20-25 year old idea? LOL.

Just curious. Opinions appreciated.
