the 328 twin exhaust has a valve which closes the flap of one of the pipes at low rpm. This valve opens up at higher rpm. Nothing wrong w your exhaust.
Next time, before you start your engine, take a look. You'll notice the right-side exhaust has a valve, which is open. Next, start your engine and take a look. The valve will have closed. At a higher rpm, it opens again.
aiya, when engine off also my flap is closed. i tot it was normal all this while.headache now. have to verify again :stupid:
thx...
