    2013 STi w/SPT exhaust.. will I need an adapter?

    I have 2013 Sti with the Spt exhaust. When I decide to go stage 2 (probably in the spring) will i need the adapter to go from 3 inch downpipe to 2.5 exhaust or is the Spt a 3 inch exhaust?

    I think it depends on the DP. The Cobb DP tapers to 2.5 inch so you do not need an adapter with it.

    Cobb you don't, most others are 3 inch. I got the guys at CNT to throw in the $30 adapter free
