Nice. I think you will kiss goodbye to body roll.I would suggest Cobra HFCs, better reputation than Berks and come with a 2 year warranty versus 1 year. Berks have been know to crack and there are some negative stories around about the Berks. I am fitting the Cobra HFCs to my Ark dual Grip exhaust and having the Ecutek remap next month. Avoiding the Berks.
