Needing a backbox for a MY06 STi Spec-D.. Something purposeful, maybe a bit more burbley than Prodrive Back Box, but not ridiculously loud would be perfect. Owner has been offered the chance to buy a straight through centre for £100 which I think he's going to go for and he thinks that twinned to something like an Afterburner, it might be a bit excessive!!

I know that the 01-07 backboxes are interchangeable..... so any experiences on slightly older Newage cars would be welcomed too.

Any ideas or links that I can pass on??


Cheers,
Grant

 

I'd wait and see how loud the straight through is with the prodrive before changing it.
