High quality and beautiful silicone hose. It is firm, tight and fits like a glove. Excellent material and seems pretty reliable. In terms of performance it feels like there is an increase in throttle response. Only reason I give a 4-star rating is the fact that it is not even close to ST200 grey, since it's far darker.
This one I could do my self. Easy job (only twenty minutes). After fitting the hose the car feels much faster. Sound is good and the grey hose looks stunning when fitted. Fast shipping.
Excellent product, looks the bees knees in grey well happy
