Well done mate.

I had a few rattles I noticed after I picked up my second-hand car recently. Probably didn't notice on the test drive as was too excited... :)

The push pins (wot thay called?) for the H6 engine cover was loose, and the water wiper bottle was hanging on by one bolt... :roll:

I had the same issue too. Then it came back from the last service with all of the clips replaced. No charge from the garage either. Just part of the service.

Great stuff man!
Actually got me thinking about my exhaust, might double check the shields around mine too!

I had an issue with a rattle from my exhaust. Custom fitted 2.25" mid muffler back exhaust with Ultrex Performance Mufflers. Turns out it was touching on the sway bar as the pipe from the right muffle had been brought back too far and was only a few mm from touching the sway bar. Had to get it fixed after lowering on STI Pinks and adding a Whiteline Rear Sway Bar as it ended up resting on the exhaust heavily.

So what I thought was a rattling heat shield turned out to be something different again. It seems the front section of the stock exhaust is double walled and the inner pipe on the right bank had separated from the outer and was rattling around inside. Anyway I had the full section between the cats and the y pipe remade 2.5" mild steel. Sounds good again.

Ended up getting the bits in black remade in 2.5"

I ordered them on Saturday. They should be here in the next week :-)
Admittedly I am surprised as how quiet the system still is with the new rear mufflers. I added some Ultrex units at the same time
