I used to have a 350i that made some fantastic noises on the overrun, my 400SE does nothing...what do u have to do to make it pop and bang..I have a variable fuel pressure regulator fitted if that makes any difference, my car also runs on unleaded.

They seem to do it more if you have an air leak into the exhaust manifold, it probably helps if the engine is set up rich too. Finally, I guess most cars have an overrun fuel cut-off which reduces the amount of fuel sloshing around in the exhaust, sometimes a poorly adjusted throttle sensor or throttle stop can prevent this from coming in. All possible reasons why a poorly set up 350 might sound better than a well maintained 400. :-(

You're spot on there Pete, just had one of my manifolds skimmed and the popping has completely gone..so are u saying it's better not to have the cars do this (ie pop n bang)? it's just that I preferred the 350s noise...yep childish a bit I know :-)
