weird sound from the exhaust area, most noticeable when car is cold but can also be present once its warmed up. Just as you touch the throttle (revs <2k) get a kind of ‘bongo drums’ hollow resonance sound from (what i presume are) the pipes
b&c claim its the charcoal filter and is nothing to worry about…
i have the stage 2 performance exhaust + pipercross
should i be satisfied by their explanation? what exactly does the charcoal filter do, and why is it making that noise?
