I bought my car a while back, and it has always made a whistling noise once i got up in the rpm range around 4500. i'm pretty sure i have stock exhaust, the only thing it could be is a gst muffler but i HIGHLY doubt it. does anyone else expierience this? personally i like it.

I know exactly what you mean. Mine did that too when I got my car. When I would rev it up real high it would whistle. It was pretty funny. My only guess is it is a exhaust leak somewhere in the catback. I have changed my catback since then and it went away. It won't hurt anything as long as you like the whistle. :)

My exhaust never whistled. My belt tensioner bearing used to whistle. It sounds like you're pretty sure it's the exhaust, but just in case, here's a link on where to find a cheap replacement for the belt tensioner bearing. http://forums.2gnt.com/cgi-bin/dcforum/dcboard.cgi?az=show_thread&om=5296&forum=DCForumID13&archive=

Oh, and you'll know it's a GS-T exhaust if it has a dual tip muffler.

disregard if you're sure it's the exhaust....
when i first got my car it would whistle quite loud with high rpm's. i thought that was how it was supposed to be, till i found the passenger-side firewall wiring plug pushed in toward the engine. just a thought
