Had a Milltek resonated exhaust fitted and yes I know the popular choice is to go non-res but I do a lot of motorway miles and was just after a slightly deeper tone and better look - so far so good.
Not sure which one you've got as they changed what they described them as a while back...
1. Non resonated. Simply one box around the rear axle and a Y pipe at the rear, now called the "race system".
2. Resonated. 2 boxes, one near the rear axle and the other nearer the front on the midpipe and a Y pipe at the rear, now described as "louder".
3. EC Approved. Comes with a suitcase style silencer at the rear, introduced at around the same time as the description changes above.
If you've got 2. from the list, mine's the same. Sounds spot on with no drone at motorway speeds but makes a bit more noise when you're booting it.
I did notice on mine yesterday (first ling trip in a while) that when it's fully warmed up, it's a tiny bit louder than when it's cold - not enough to worry about though.
