Well I fitted this a few days after I got my hands on it and it was just a tad too loud for my liking. However that said, I'm the guy that put both foams back in the sound generator!
The car does sound good though from the outside on a drive by, very good in fact. I took it down to an industrial estate I know with a mate. The estate has some long quick stretches so ideal for car testing etc. On a drive by it sounds great, like a proper sports car should, not a humdrum saloon like it sounds as standard. It was just a little too loud for me inside, could be my age I guess! I did do a few sound clips but I wont post them as like most they dont give an accurate representation of the real thing. Even when listened too through a decent quality surround sound system. In fact the clip of one already linked/posted on this thread is a better real life representation than the ones i managed.
I thought I would give it a week or so to see if I got used to it, but I ended up taking it off. The car sounds really crap now without it and am probably going to go down the back box route in the very near future, wont be a DLV though that's for sure! :thumbsdown:
Its actually a real shame its too loud for me as it did liven up the throttle response,which is no surprise really as you're removing a lot of the restrictions in the standard system. Plus the standard M54 throttle response is quite sluggish in my opinion so this was most welcome.
I can confirm (as previously stated) that its a Direnza system which the Mini folks rave about and its well put together/good quality. Certainly if its not too loud for you its a great product and amazing value as the asking price is what some people are paying for just a back box delete.
