A few months ago a few people complaining about the tips discolouring, pitting and bad welding on the Mountune (Milltek) exhausts. Id recomend you call/email them once ordered and ask them if this is resolved.
No issues with my V3 Mountune. As a retired engineer(MIMechE) I was very impressed with the quality. I was shown the rear high flow clean cold rolled stainless st. rear box with over axle pipe before fitting comprising superb neat clean TIG welds and high quality V clamp connections. As for the rear tips, still gleaming.
