Track friendly backbox
Hi
I have a full decat 3 " japspeed system on my v4 sti type r, and wanting to put a track friendly backbox on it and was wondering if i could just swap the backbox or if i would have to swap the whole exhaust?
I am also guessing i would have to get it remapped after swapping it?
Any advice would be great

I'm using a Fujitsubo gikken one piece pipe on my decatted classic. It passes Brands hatch 105db noise tests at around 96db. The trick to keeping a decatted system quiet is to use a resonated centre pipe. Ive been told that a map tweak isnt essential but I dont understand how changing the flow of the exhaust gasses doesnt effect the combustion so I would reccomend a map tweak
