Will this backbox be too loud?

[Danez 6 1 Cars]

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

I was thinking of getting this sportex one

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. I know it's an arbitrary question based on peoples own opinion but it'd be good to get an idea. It's only a backbox, I'll be keeping my cat on and the description reckons it's not too loud but be good to hear from people with experience.
cheers

Sportex are reputedly pretty loud. Turbos have a silencing effect though so a loud exhaust usually isn't quite as annoying on a turbo'd car compared to NA.

I removed the back box completely from my old 306 diesel turbo back when I was a yob. And made a pipe out of a 205 down pipe put in backwards to go in it’s place. It wasn’t really that loud. So with a silencer it should be ok tbh.
