I currently have the basic bolt-ons like TBE, IC piping, and intake. I figure my next step is to upgrade my O2 housing. The problem is that I am on a budget and know that the EPM dump is more expensive than a regular housing. What I want to know is if there is a major difference in power between the dump and the normal housing?

 

i believe the 02 dump makes like 10whp more than a regular 02 housing..

 

It'll give you more power, however, it'll be a lot louder when your WOT.
