remap needed? swapping japspeed 3" backbox+center to blitz nur spec r?
 

Hi,

Ive got a late 96 wrx with a japspeed 3" system with the sports cat downpipe - already mapped. Found out ive got a gaping hole in the backbox and needs replacing for the MOT - is it just a straight swap over to a blitz nur spec backbox+center?

cheers.

in theory it should make little difference, but I would advice just getting whom ever mapped it to check it.. if the exhaust the car was mapped on was restrictive slightly more than new one etc it can effect the map.
