So many places and same price, so dont think it really mattered. Best option was nearest place to home so it was Larkspeed in Leeds. I phoned them direct, not through ebay. They obviously honour the ebay price. Cant wait Dont think I`ll be disappointed, eventhough the oem exhaust with the stillen intake sounded very nice, so hoping for a slight difference / improvement. Just wish I understood the re-mapping etc so probably get more from the Z.
Will post up when I get fitted, which going by the weather will be next week Will be staring at it for a few days
