Will this exhaust be too loud for a daily?

[Danez]

I'm needing a new back box for my phase 1 306 1.9 TD

I was thinking of getting this sportex tailbox

But I've never had any experience with sportex. Am wondering if this would be suitable for a daily. Not too loud for my neighbours or going down the motorway but sounding decent. It's only a backbox and the description reckons it's not too loud but be good to hear from people with experience.
cheers
