Im looking to get a good oem axle back and find out that these are my options for stock. Need something that flows good. I don't want nothing fancy like ws2 or greddy so dont be telling me to get those. Any recommendations?

 

Year/make/model of your car might help.

...and how are we supposed to compare an AP1 (S2000) OE exhaust with it's dual mufflers, and an RSX single muffler?

Am I misreading your question?

 

There are plenty of aftermarket chambered mufflers out there that would flow better than a honda OEM muffler and be just as quiet. That would be your best bet IMO.

 

although the s2k has dual eshausts it can be done,remember he only wants the axle back. have you looked into the new civic SI exhaust??? the sound nice and they are really quiet

 

I'm going to be putting one of them on my EK hatch...and I was just wondering which one would be better flowing and better bang for the bucks...and yes i will be welding it on to my car...As for 07 si oem muffler, not quite my taste..itss still a little loud for my straight pipe..
