Hi Everyone.
I bought a brand new 2008 GS460 in July for a VERY good price. One thing that is bothering me is this exhaust leak noise coming from under the front of the car near the engine resembling a manifold exhause leak. it's only there once the car has had a chance to warm up a bit. The dealer initially said this was a normal sound. When I go in for my 5000mi naint I'm going to mention it again, but was wondering if anyone else that owns one of these 2008 GS 460s has noticed a similar sound?
