Rumble on the cheap! This pipe from Nameless performance satiates all the loudness you want without the weight and still has the beatiful 4" double wall tip on the end. Cabin noise definitely increases but not drastically. With a decibel meter I went from 75 avg (stock) to 83 avg. Crack the window and it's a whole another level - the roar above 3000 rpm is great and guarantees head turns for better or worse.

I would recommend having a dremel/grinder handy as the stock bolts were completely rusted to their nuts - and to the flange, and needed to be cut off. It goes without saying that extra hardware is required. Gasket came with the pipe but no hardware. I used M10x1.5 which has a 17mm (11/16) hex head. Stock has a 14mm (9/16) head.
