i dont rate laser too much quicksliver do better center zorsts for the cooper but if you whant a bit more noise the acutul
jcw back box on the sound kit is good just the minis manifold is crap get a janspeed manifold from lohen then youll notcie a diff in sound
also a piperross induction kit for them too would be nice ive got one on my cooper not the loudest thing but then im more into a proper racing sound than a chav my motor sound
