and a piper back box? any real difference?

[JamesR]

Piper will have better build quality, will sound better, fit better, look nicer. And wont fall off on the motorway ( if fitted correctly ) and will last 10X longer.

We wouldnt all buy Things like piper, suipersprint, magnex etc if they where the same as that crap.

thats a universal box that comes with a crappy flexy connector. ive never read weld it on and diy fitment in the same sentence lol!
will pick up a decemt back box second hand for that or new for not much more
