A quick video of a Y-pipe(midpipe)only modification to a Nissan GT-R. The rest of the exhaust is stock. The Y-pipe drops 14 lbs of weight from the car, and frees up 20 hp. The exhaust fits 2009-2012 Nissan GT-R's, and is an easy six bolt swap. The Y-pipe is resonated, so it gives you a more aggressive sound without being too loud.
