If you get your car up on ramps take a look at where the Milltek almost meets the rear prop shaft just below the circular disc shaped part, both of my Millteks have suffered almost a circular saw action where this part of the prop shaft has touched the exhaust whilst spinning, I'll start a thread and post some pics later today as I'm concerned this may be a safety issue, my car is on stock suspension and the last exhaust fitted by Millteks own specialist fitter at HQ so I think their maybe a design fault - ps I rarely carry passengers so not a weight issue.
