For sale is a 2.5 downpipe. It needs some pin holes weld up. I can weld it if buyer request but im no pro at welding.   The mid pipe has a o2 bung on it. It seems to be 2.25 i think. The cat is gutted.   Asking $75 shipped for the downpipe alone or $100 shipped for both.   Only the stock one wire o2 will be included if buyer wants it. Has less then 100 miles on it.   http://i160.photobucket.com/albums/t173/zapien85/starquest/IMG_20150505_1753222381_zpsmgdtjmu9.jpg http://i160.photobucket.com/alb

I just picked up one of these combo thermometer and voltmeter gauges that plugs into the 12v outlet. It works great and matches the red from my arm uego gauge.   It's in Amazon as a Drok 180037 model   http://ecx.images-amazon.com/images/I/41F3W8e52XL._SY400_.jpg
