still looks an alright bit of kit, been tempted by one myself, just didn't want you paying the likes of £700+ for a custom system, if it wasn't, £320 is a good price if it is the eBay one, £70 for fitting is only an hours labour at a garage, as long as it seals and flows okay its a good buy, great work so far, keep it up and i look forward to seeing more updates.
