um, i thought some of the positions for the hangers were different between the type-s and base.... i might be wrong but i don't think it ended up being as easy as geting a race header and type-s exhaust... but someone correct me if i'm wrong.... there are lots of old threads on this.
but the b-pipe thing is not making sense to me, Ooi.... unless you are only planning on getting an axle-back exhaust, then you would need a b-pipe of some sort, but cat back exhausts include the b-pipe.
