Post BPM Twin Dump Down Pipe

I was told that this down-pipe wouldn't mate to any other mide-pipe, but a friend of was able to fit it with an Apexi cat-back.

You need to drill an O2 bung on either the down-pipe or the mid-pipe because the BPM down-pipe doesn't have a bung.

Does it have a cat? If it doesn't, you don't need the sensor. Just remove it and put a resistor in the appoprate spot.

Mine has a bung, you sure it bolts up to an Apexi exhaust?
I was gonna buy the B&B DP because I want the apex GT.
Need something with CARB papers.

You don't need CARB papers for a catback b/c they are all legal. Any and all other aftermarket parts are not CARB exempt as no distributor has invested what it takes to get an EO number for Subaru products, because the market is so small.

Don't need them, just like having as much ammo as possible when dealing with the popos. By default I am guilty of an infraction anyway=driving while black.

I am often subject to watching cops dodge around me looking for a reason to pull me over. I'm even running a front plate these days. Yes I had a chipet pull ahead after following me for a couple miles, when she saw no front plate, she slowed up and pulled me over. I could go on...
