I have recently noticed that when parking the car in the garage that there is a horrid eggy smell if i reverse it in (so the gases are more contained in the garage if that makes sense?) Is this a problem or could this be linked to my new exhuast full system?
On a related question if i rev the engine when its stood still, as the revs drop it almost sounds like the exhaust is blowing somewhere, but there is still stuff coming out of the tail pipes. Im pretty sure it was like this when it was fitted and the matey said it was fine, but my memory is comparible to that of a 90yr old! As this is the first "performance" exhaust i have had im just wondering if this is normal?
Thanks in advance for help.
