Had it done up for a customer, but he sold his car and needed it put back to stock.
It's a complete bolt-on (direct bolt-on to the stock midpipe flange) for a g35; should bolt on to a 350z, but the pipe may need a slight bit more bend on it, not certain.
Definately weighs far less than the stock axle back, and has a bad-ass sound to it - nice, deep growl, almost V8ish. No rasp anywhere in the RPM band.
Only thing it doesn't have are tips (it has a pair of temporary tips, you can add your own if you like)...ask for pictures if there's any interest.
$180 OBO.
