I no longer need this. I have a sohc so I need all the power I can get :P It was on my car for less than 500 miles(under a month).. It went on when my turbo setup went on and I just pulled it off today. It's 3" and the 2 bolt flange is TIG welded on(nice weld). Excellent shape. $60+shipping

Also have 2-3" exhaust clamps. $5+shipping for both. I have vouches. Here are the pics..
