Need help finding catback exhaust

even though it will rust out, found http://www.autoanything.com/exhausts-mufflers/61A2451A0A0.aspx
244 /w free shipping

i checked out stillen and also found nothing, checked a few other named brands and they only have stuff for the newer sentras.

I am also willing to spend up to 400 now, and I have to be more open minded to 2.25-2.5, it will be fine i guess, I just don’t want it to sound terrible like the boyzz i see out on the streets, so there has to be a decent muffler in the package.

thanks for the input
