slowmtree IMO, your 'Right Foot' is the best valve possible...to gauge exhaust volume/sound.
Factors to consider:
- Always 100% reliable, infinite 'right foot' volume adjustability
- Never plagued w/ rattles, defects or failures [i.e. mechanical or electrical]
- No worries of spare parts availability or manf out-of business
After three different exhaust set-ups, then researched 'exhaustively', no pun intended

, valved v conventional systems; opted for a single, integrated
high quality system which
sounds unique, exotic & AMAZING.

I chose to go 'full beans' - -My system set up [Stage II, cat-less] => Supersprint:
- Down pipe section
- X-pipe section
- F1 Race cans
Supersprint fully supports, offers a plethora of options/products for e92X M3s to suit 'sound taste', budget, 3yr warranty, and more with direct purchase possible from Italy.
PM if interested learning more...GL on selection & enjoy!
