I was wondering wether the sound coming out of the Prodrive BB after the full PPP upgrade would be louder, quieter or the same as just a Scoobysport BB.

cheers,

Greg

Much much quieter off boost, small throttle openings and low revs - quieter on boost and high revs but with an entertaining whoosing/jet plane type noise

The sound of Mike's (RB170) RB5WR coming passed at high speed is like a jet plane

As above - quieter off boost, just a nice background burble when cruising. When giving it some... mMMmm... back windows down please

Anyone tried doing this through the Dartford Tunnel? Best thing about it
