I have a 56 plate petrol VRS and while scraping to frost off the car this morning while the engine was running I noticed that the exhaust fumes were only coming out of the right hand side of the twin exhaust.

Is this normal? I though the fumes would come out of both sides as they are close together.

Cheers

normal I would say, at Idle there will be less pressure, so its not unlikely for the fumes to escape via one tailpipe
