Rattling exhaust
Hiya
A quick question. I have a G-pipe/secondary silencer delete (great sound, by the way). This morning my exhaust has a big rattle which sounds like a Caribbean steel pan band! It seems to be RPM-related rather than speed related. Is it likely to be the internals of the primary silencer or cat that is rattling? Has the G-pipe caused a blow through of that silencer? Many thanks Chris |
It normally happens on cars with primary bypass, where a secondary muffler splits on the outside (vertical split thru welded together top and bottom half) - ask me how I know and why I have 3 spare mufflers...
To say that I would inspect your primary for sure. |

Thanks chaps. Unfortunately I think I have found the rattling problem. The main fan is touching the fan housing and causing the rattling. I've been told by my garage not to drive it as the tolerances are so tight - will have to get it recovered and taken there for it to be looked at. They say it might be the alternator bearing so could do damage if driven .
At least I know what it is! Thanks Chris |

To say that I would inspect your primary for sure. Happened to me after a track day. Sounded crazy loud on long drive home. https://lh3.googleusercontent.com/eI...=w1600-h679-no |
