Hello chaps, thinking of changing the exhaust back box on my sti 2008 uk hatch . I miss the note of my old classic I had . Main question is , as this is back box change only , would this upgrade require a remap ? mab invidia or Hayward and scott ..... thanks much .

 

I recently asked my mapper if the map on my car would need checked after changing the mid section of the exhaust and his reply was No.

 

and that's the mid section . so id say from that a rear box change prob ok , I think maps needed more for closer to engine like down pipe etc. thanks frank

 

Be careful to check your existing mid section connects to the backbox of choice, majority use their own variation of mid section. Not like previous newage & classic which are all std length generally

 

yes id love to think my center pipe could be used but according to scoobyworld haywood and scott require there center section to be installed an extra 200 I think ! total bill nearing 720 ish . im starting to think of getting my oem set fixed for now using a flange donut spacer and hose clips with het resistant hermalite... not sure at moment.
