Which backbox???

[pinky]

hi there, iv got a clio, mk2 ph2 1.2 16v extreme and i was going to get a powerflow backbox fitted tomoz but iv just heard some bad things about them, does anyone know anymore? or if they would recommend any other? for around £180 fitted.
can get a universal magnex twin 3" round backbox (not fitted) for £109
does this seem the better option, how much does a garage charge for fitting one?
and im not into japcans!
Cheers

You wont see an increase in performance its jst for sound and looks.
