Meabh,
My Brooklands Roadster 3.7 already has the Aero Racing Sports exhaust fitted so it is louder than the standard system (I had a "bespoke" Roadster 3.7 previously to compare). With the side exits, the exhaust note is deeper but not noticeably louder
from inside the car. The sports silencer remains in place and the standard tailpipe which has a resonator at the tip is replaced by the side exits which do not have a resonator. A local (Ayrshire) custom exhaust specialist made the exit pipes for me for a total of £200.00.
Regards,
Don.
