The hellion kit is one of the best single turbo kits I've seen for Cobra's...very finely manufactured for a superior fit from what I've seen in pictures of them installed on cars...
it has ceramic cold pipes and stainless hot parts and high quality for the other stuff. it or hellion would be my choice for my fox. and with a 03 cobra in muscle mustangs and fast fords hellion power systems kit the cobra made 847 hp in stock form
