Noblesse has a center out exhaust that pairs with the Style Sports rear bumper. Actually there are two exhausts from them. However, the one I am interested in is the 'racing' version.
http://noblesse.shop-pro.jp/?pid=62077575 My problem is that I can't seem to find the size of this exhaust... 2.5" or 3.0"?? I searched the main website and translated most of it through the web however no notes on piping sizes. Could someone assist me in finding these numbers? This would be so much appreciated.
