Does anyone know if Blitz do a back box for the 03 sti type uk and whether it will connect onto the existing centre section. OR if i buy the nur spec r system whether this back box will fit onto existing centre, then i can fit blitz centre section later.
(With it being a brand new car dealer will only let me fit back box because of warranty)

STi M'8

If you get the back box only, it will fit as it is designed with a reduced entry to bolt on the 2.5' stock center.

BB and center Blitz do not exist in a "short" version to fit the 4 parts (2 cats turbo back: DP, cat pipe plus center and BB) european WRX systems as far as I know.

If you really want to, you can bolt a classic DP (up to 2000) and then bolt the Classic or japanese Blitz system. I did on my STi03

Note that a classic catted DP will not fit STi without serious mods as M6 gearbox I way much larger than M5 !
