New style PSE - dB Noise Level ?


Recommended Posts

Hi all,

I've had a friend make me a set of 'PSE' exhausts from a set of normal exhausts (ebay - £50!).

I aim to fit these to my MY99 3.4 but I also do a lot of track days. Here in the UK, the noise regulations at track days are fairly tight for 'noisy' cars so does anybody have any idea of the noise level for a new style PSE (or large bypass pipe as per my modification..!)

Some tracks are as tough as 98dB (102dB is average though) - I believe the standard exhaust is already 95dB @ 4500 RPM... :-(

Thanks guys..

PS - Invaluable info from the vast PSE posts - great stuff.

Hi,

not sure what the "official" figures are for PSE, but, and this is perhaps a bit of a crude measurement, my bro's mobile phone has a built-in sound meter, so we checked my PSE and at 5k rpm it registered 114db (same as his Tuscan S)!
