Hi guys, yes my exhaust is a dual Apexi N1, same as mr_fanny, seperates about half a metre from the all the way to the rear.... I gotta admit, it's the best exhaust I've seen when it comes to looks and sound... Everybody has the usual 5'' tip single, so if you want something different, this is the exhaust for you...
kg- if your looking for a dual system from turbo back, then u need a HKS system, i think Doughboy had one for sale to suit r33, although it was suited for 'race' purposes only, as it didn't have any 'cats'....
