Title: FD Silencer noise reduction
Post by: noyzboy on March 20, 2006, 08:58:55 PM
Changed out the 110mm drainpipe that came with the car. Fitted a Racing Beat twin outlet catback.

On the meter @ 0.5m from tailpipe@45 degrees@5000rpm( as per RAC)

"Prof" Sports Muffler  94dBA
Racing Beat             91dBA

At cruising speeds, now I\'m listening to the tyre roar, and I can hear the engine and not the exhaust. Big success as far as I\'m concerned

Anadin consumption much reduced.
