   I am considering a new exhaust back box.
   
   I am going to retain the Magnex center section with the silencer to keep the noise down. I have access to a friendly rolling road, just don't want to waste any money.
   
   I want the best free flow back box to add the most top end power.
   
   1. Kam back box 2" outlet
   
   2 . Super sprint 2" outlet
   
   3. Saxsport
   
   Has anyone got any power runs before & afters to show what proven power gains.

   I personally do not have any proven gains but I have a relative that gained 5.6 bhp from a piper backbox. Was on a standard VTS just a PIPER backbox. I love them and think they are ae awesome but not sure if they give the best power gains.

   simple just take out your centre box a magnex and custom exhaust place will do it for you makes good power that way also if you have a magnex system they dont join like normal saxo exhausts so you would have to replace both

   Why does it not make good power using 2 boxes ?

   You'll get best power gains from the Saxsport cat back or the Superpsrint cat back. Bare in mind the Saxsport is a sleeve fitment therefore you will have to get rid of your magnex centre section and replace it with the Saxsport. Ive got one for sale aswell if your interested?
