HKS or Blitz, just thinking about a back box for now as I do not want to invalidate my warrenty on a full system on my new Sti 8.
Any replies most welcome

regards "MADDOG"

 

It's all down to an opinion ! I used to have a HKS Supa Dragor on my WRX & it wasn't much different to a standard sound & that's with a decat down pipe. I have changed it to a Blitz Nur Spec now & oh boy can you here me coming.... It just opens the flat four up & it sounds great But I know HKS do other systems that are loud like the Nur Spec.


Cheers

 

A backbox can invalidate your warranty depending how friendly your dealer is.
