Noise Reduction?

[Ferb]

Has anybody used the SupperTrapp clamp on Disc's for extra silencing? Are they any good? My car is 101db static, needs to be 100db static, 98db drive by for Donington

a mate used one on his XTR2 westfield, created so much back pressure, it split his silencer in 2

a supertrapp will definitely do the job - usually good for ~3dB. be careful though - i've heard horror stories about them creating back-pressure and knackering engines. unfortunately i'm not mechanically minded enough to know what causes it and which engines are worst affected - so you should definitely seek advice from someone who knows before fitting.
