Hi all,have now had my 370 for 6 weeks ;a 60 reg gt in gun metal bought from a 68 year old man who rarely used it.Had 4500 miles on the clock and smelt brand new.I gather every time he took it out,he washed it on it's return.And not one mark on any of the alloys.Anyway at some time shortly I'll give you my report on the car itself.Now to the point.It's too quiet.We all know that.It's odd to me that nissan give the car an almost refined exhaust note whilst all hell can be breaking out in the car with so much road noise.Two extremes.Anyway the exhaust has got to go.Have heard quite a few examples on utube but is it me-they still don't sound loud.I'm not looking to change the thing to find very little difference-did that once with an mx5 and put a power-flow on with not a huge amount of difference-and I only want a cat-back and nothing else.So those of you with replacements ,give me a % rise in noise.Is it 10,20 or 30% rise .Have seen Invidias reasonably priced and borlas which may well not be.Your feed back will be greatly appreciated.Am in the North West outside Merseyside if anyone has one fitted and will let me listen.best wishes to all,Derek
