To pass smog here in California, turns out that I need to replace the whole exhaust muffler and gasket in my 1998 DB7 volante. I also think that I need a new fuel pump. Dealer quoted $2700 for the muffler set. I was curious if anyone has bought aftermarket exhaust/muffler kits, or knows where to find an OEM set? Been searching online for a while, with no luck, any help is appreciated! Thanks!
