Recently bottomed out my Z on a stupidly high speed hump and grounded the mid section of the exhaust. Now (especially when cold) it's making a loud rattling sound when revving.
Took it down my local Quick Fit(!) just to get it up on the ramps and have a look. No external damage visible, but if you bang the pipes, something metallic is definitely loose in there!
Anyone got any ideas what may have broken in the pipe to cause this and as a result, are there any performance or maintenance worries to consider? It seems to be running fine but it just sounds like a dog!
On the same subject, I was considering having the car decatted. However, it's a UK '93 vehicle and I've read somewhere that you can only decat pre August '92 cars (something to do with the MOT and emmissions??)
Any help appreciated guys... :confused:
