EPM is the way to go!

 

+10000

 

I made my own since no one on the market offers a true 3" o2 housing. I v-banded my o2 housing and added a SS flex section in the downpipe. it also clears the ACD

EPM doesn't even sell a 3" o2 housing....they all neck down at the flange.

 

For a recirculating o2 housing I have heard WORKS makes one of the best

 

I go full boost every day I use my car thats for sure. Not all the time but a lot of times each day I use it. On the other hand I enjoy a fairly quiet exhaust. I had a loud exhaust in my old RX-7 and also in my Integra but try not do do the same with the Evo. Maybe I am getting old. He he!!

 

^^^ some of us city folk can only dream about having enough space to fully boost everyday ;-(

and i get tired of civics chasing me

 

No reason an o2 dump can't be on a DD. During a daily commute, you really shouldn't be driving hard enough to open the wastegate anyway. I guess maybe I should practice what I preach I don't DD the Evo anyway.

Either way, o2 dumps are proven to give very good WHP gains. If you want to sacrifice power to be a little more quiet, that's perfectly fine. But if you want the maximum power out of an o2 housing, an external dump is the way to go.

 

well i know that the emp is proven to give alot of power but i really dont like all that sound i just want to keep it simple i guess it would just be btw the Invidia, Titek and the Helix i dont think a want a 02 dump just yet

 

Keep in mind there are some tracks w/ noise regulations that won't allow open dumps even if your car is track only and not DD.

 

If you don't want an open dump 02 housing, I'd just get the Megan. Cheap and makes good power.
