your plans of a 3" exhaust with headers are not sufficient to maximize power in a BP 13b
you Must use True DUAL Exhaust system like the one RB sells (or you can custom fab of course) to effectively utilize the flow from the bp.
how do i know? I asked Jim Mederer @ Racing Beat thats how. and in case you dont know who JM is, he's been engineering RE's since before both of us were born.
so do it the right way or dont bother cuz if you dont do it the RIGHT way you wont make the power you want.
nah true duals loose out because they dont collect. they work on a stock port. the mazda factory, and even racing beat havent run true duals since the early 70's.

umm. ok j9 if Racing Beat hasn't run duals since the early 70's when their weren't even rx7's how exactly did they r&d all the rx7 n/a stuff? answer me that.
all I know is when I talked to JM he told me (just as their website says*) that the collected is for streetable and the road race (dual) is for racing applications.
and i know for a FACT that a true dual system gives more high end power than the single how do i know?
because i have friends with both and have compared both cars and the dual definetly without a doubt had more at the topend.-=
my own .02
but maybe others have had different results.....

Thats the thing, with a standalone, expect to get more than 200hp.
Look into Megasquirt. They are inexpensive, and work well. Or, since you are S4, Rtek 2.0.
You can get a Haltech or Microtech all day long for under $1k.
