Strange rattle / metal shaking sound 99 Boxster

[Nimbus117]

Mine did this but the rattling was from the rear of the car, the two lambda probes on the LH exhaust were lose and rattled on acceleration/deceleration. At steady throttle there was no rattle. I could only hear it when going less than 30 in low gears as road noise drowned it out going faster.

Hi Nimbus,

Your situation sounds exactly like mine. Its in a local Porsche specialist shop as we speak. He said I have a couple small exhaust leaks as well as need some things "tightened up" under there. Ill give you guys the more technical information when I pick the car up tonight.

OK,

So I talked to them, they pulled the entire exhaust and found a few leaks they fixed for me, replaced ALL heat sheild bolts. They said it was providing the majority of the loud noise and rattling. They also replaced two exhaust clamps. The bill seemed quite steep tp me though..... 2.5 hours of labor and the clamps was $348.00...? If I had known that I would have put a new exhaust on.....

Ah the joys of being a European car owner.
