Let's see some data results...from this other company. All I have seen are claims of this or that from a prototype they have. We provided proof many times of all the claims we have made about our O2 Dump.
I'm not into a bashing war, but seriously; we are the Only O2 Dump Housing producer that has pruven our product over and over/again and again. And with well over 150 units sold (WorldWide) we are the best seller too...there must be a reason behind that.
If you only knew how much time and effort that has gone into our product you would then think $258.00 is a bargain....

 

AMEN to that. I've looked also and all I found when looking for stats and data to prove gains EPM were the only results. And like Q said, they've got many EVO owners that can back them up with the gains and how good of a product it is.

Hope you don't mind me having your back there Q.

 

I searched around and only found viable data for the EPM O2 dump.


That's why I bought one.


BTW, Q I just took delivery of my EPM 02 dump housing today .

I haven't opened the box yet though.

 

EPM FTW...product & customer service were both awesome...i had the QTP electronic cutout downpipe on my car before i put the EPM 02 housing on...after installing the EPM 02 housing and before tuning it felt like my car had the cutout open...after tuning...even more bad*ss...i do like QTPs products but i went with EPM 02 housing and i am very happy...
