i love the milltek sound after listening to loads on you tube but seem to have a poor image on here lol now i had a jetex on my audi a4 turbo and the build quality on that was 100% only issue was i ordered the res system and it was FAR to quiet so i chopped the mid box out then it sounded spot on! the Jetex systems are as low as £320!! which is good to say have lifetime warranty and are 2.5'' madrel too
