I'm looking for a replacement backbox, there's nothing wrong with the one I have now except that it's a bit loud for my liking and also it pokes down from the bumper more than I would like! Will update with a pic when I can, but just wondering if any1 knows of some low-ish profile backboxes! I have a 172 cup with the bumper cut in for the exhaust tip to show but the big dangly backbox is abit of an eye sore! Believe it's a prospeed one(?) any recommendations?! My friend has a miltek and it sounds lovely!
