Well, it seems like its common thing. I phoned powerflex yesterday and although thier website says 1 type of mount, the guy thought I would need 2 different ones.....but he couldn't be certain which ones I would need either. I phoned Demon Tweeks......who powerflex suggested I talk to......and they couldn't even tell me.....he said I would be best to try and measure the ones on there and match them to the diagrams on the powerflex website. I can't believe no one knows what exhaust mounts I need.
