i appreciate your inputs!

WOW .. interesting conundrum ... the stock set up was too ZZZzzzzz!

Most of us did Akrapovich, Turner Muffler delete or Eisenmann as this engine is too sedated for sound vs the outgoing V10 in last Gen that I still miss the exhaust note on

I know I have done the Super Sprint catless down pipes (gives you the turbo spool whistle and CEL) and then the Akra Full titanium exhaust ... then Dinan Stage II ... they claim with my set up and Dinan Stage II I am still 25 Hp and 30 ftlb higher than stock with Dinan Stage II set up

The more free flowing the Exhaust seems to free up Hp from what I have seen.

Perhaps those with MUCH More KNOW how then me (Big Brain, M6 Coup ) can Chime in to help!

Enjoy the Addiction Bro ... and you can always Paddle shift to keep the RPMs lower in a higher gear to keep the car quite when need be
