Sorry, we discontinued this item. We no longer make a 3" because our 2.5" system will flow over 400 hp. We proved we can do it but we dont want to charge you for something you dont need being that the 3" cost more to make and it does not have as good of a clearance as a 2.5" does and it weights much more.
If you must have a 3" system we can only do it locally as we tossed our jigs for 3".
