I did the same as twowheelin. I actually took that picture to the shop. They did that plus replaced my resonator for $200. I then had to pay anouther 60 for a bigger resonator it was a bit to loud. I know they aren't mandrel bent but the bends are so samll I don't think it lost much in inner diameter. It defenitly feels like it has more power. It seems I gained some low end torque also. Only downside to this set up is it is a bit loud. $65 sounds good to clean up the stock setup though.
