I am having the exhaust can replaced by Powerspeed and wondering what noise limit to go for balanced against having too large a dustbin on the side of the car.
They are suggesting a 7" can to cover all bases but it dominates the car whereas I am thinking perhaps 6" might suffice. Engine is a 1760cc Xflow with 4-1 primaries.
I am in the south so likely to visit circuits like Thruxton, Goodwood, Castle Coombe, maybe others in Midlands. Castle Coombe has limit of 100db(A), which is measured at ½ metre from the exhaust outlet at 4500rpm. Goodwood has a 105dB track day but I think they do quieter ones. Thruxton says Maximum 90db @ 0.5m/45 deg.
Confused and looking for advice on this one please. Cheers, McB
