Ours is a 2004 (2003-2008 generation), so I don't know if that still applies... anyway, the insulation on both the hood & firewall is very thin (at most a 1/4 thick), so I assume that upgrading that would help. Anyway, I'm also thinking of sound-insulating the whole interior, so I'll see how much that alone helps.
That exhaust tidbit is interesting, though.
