The valved option is way more expensive as you have seen ,the valves are open in S mode at idle and then between 1000 and 4000 rpm they are closed in gear 1,2 and 3 and then open again above 4k ( some crap about drive by noise legslation )but open at all times when in 4,5 and 6 when in S mode
an option may be to go for a second hand one , they come up regularly on here and ebay when ppl move the cars on as dealers won't give more money in a trade in and some people don't want them, the whole original exhaust comes off behind the cats in one piece so is easy to remove and refit if needed (transporting or storing it may be tricky but some places will keep your exhaust for you while the milly is on the car ), the valves don't really give trouble , at worst they may stick after a long time , but some lube sorts them out. As I said I had the valves disconnected a while which would be the same as none fitted obviously ,and it was much louder and more intrusive inside , and I have the resonated centre section on mine .
basically its 25mph per 1000 rpm in 6th gear so quite low geared for such big engine. Cruising on the motorway your at about 3000/ 3300 depending on your mood

so well above the drone , its not an issue then at all
