2004 Maxima SE owners

HI everyone,
What do you think about the stock tires on 2004 SE (Goodyear Eagle RS-A)?
Has anyone already replaced them and with what?
What do you think about Continental ContiExtreme? They sound like a great deal.
I also noticed that the Maxima doesn't have a true dual exhaust system. Has anyone made an attempt to modify it and how can it be done?
Thanks

the Contiextreme's are great tires...at a very good price too. go for 'em. the exhaust system on maxima's is pretty damn good, don't worry about a true dual setup, it wouldn't do you that much good

i've got contiextremes on my 97 and they do great in the rain and make absolutely no noise
