If I ran this with test pipes as well as a cobra unresonated back box would it be very loud but pass MOT tests fine? I like the volume of my cat back with stock cats because it's my daily, would adding test pipes and this single HFC make it overly loud or raspy?

Its not that loud, sounds more meaty, a little rasp but not much, some cars pass, some dont.

Thats the exhaust setup I had on my car (test pipes, motordyne xyz with hfc and cobra non-resonated), I never had any problems getting through the MOT but then I went to a specialist for my MOT tests and they fitted it in the first place!

 

I have a few videos on youtube going through tunnels with it from the Wales meet a few years ago.
