So yesterday I drove down to mij in Walsall after a recommendation and ended up having new backbox from just after the rear silencer....now I'm tempted to get all the rest done, cat back and maybe y pipes,This is there own custom exhaust system and I'm really impressed with there work, looks as good as anything you can buy and sounds exactly how I said I wanted it to, not loud on tick over but a nice deep loud tone when put foot down, highly recommend....mate has a cobra and we have both agreed this one sounds better.
