I have a 2005 350z Roadster and had a longlife exhaust fitted top quality work I think,went bit to conservative as at the time want to be similar noise to the orginal but wish I had gone for a slightly noiser set up...! :yahoo:
But to be fare the guy who fitted it did say I could change it if I wanted to,which I might well do
as for the lifetime warranty thats transferable as well so I was told which is good when you come to sell in my opinion ;)
Plus they are different to everbody needs in away
