91 owner needs help

Does anyone out there know a good place, online or in the twin cities, minnesota, to find mods for a 91 maxima? I'm specifically looking for a y-pipe to upgrade, and if needed other exaust components. Also if there is a supercharger available out there that would interest my very much. Anyone with answers to those questions or any wheel/tire advice, please post a response, thankyou.

I don't know about in the cities, but if U are willing to take a 5 hour road trip, I could direct you to someplace here where I'm at.....

They don't make a SC for 3rd Gen Maximas, I don't think.

If you do find any thing please let me know. I have a 92 with the DOHC and i can't find anything either. the only thing tha I was able to do is spray it.
