Scott: My ad was pulled but to answer your question regarding the V12 Vantage rear muffler vs. the Milltek unit... The Milltek drones on the highway but around town its a really cool sounding exhaust. The V12 rear "box" is the same as the Vantage S box. It's lighter and less restrictive than the original box box it comes with the by-pass so it won't drone below 4400 RPM. fee free to email me directly @
