Hi, I'm looking to getting a quickshift from scoobyworld for MY00, heard contradictory comments on them, been told I'll only have it on for a couple of days as they are so noisy, is this right ? I can see there are different priced ones 50 quid and 110 quid is there really that much in it or is that just branding issues ? Are they pretty easy to fit ? Cheers in advance
