It's interesting to me that a few vendors on here are making statements about our products without much knowledge of them. The O2 housings currently on the market are built with different methods of reaching the end result. Our product was designed to build the most power for the least money out of pocket, all without sacrificing build quality. Our flanges are mild steel welded to 304 stainless tubing to help reduce the costs involved.

Some of the statements made on here about being a poor design, exhaust leaks, things of this nature, are not solely true. Not to say there haven't been challenges along the way with our product - all to which we have addressed and offered anything from a free replacement to a full refund, some to which the customer simply didn't take us up on (one is mentioned above). We strive to provide unparalled customer service and very nice quality components. The poor design comment seems to be off the hip, but understandable by looking at our part. As hundreds of customers have reported on this site alone, the reduction to the 2.5" outlet does not hinder the performance. Which should go to prove that just because you look at something doesn't mean that it doesn't work well.

If any of you have any questions regarding our products, contact me or Q and we will be happy to help answer anything. Too bad Indy isn't on here much anymore as he commented on the how well the design works. Maybe our distributor in FL can chime in here and add his comments on why our product is on his top 5 list of suggested purchases for the money (bang for the customer's buck, so to speak).

Again, if there are any questions regarding our product, contact us directly and we will be happy to help.

The JMFab O2 Dump is a very nice looking product. The quality of the welds and fitment of the various tubes are of good quality, no question. There is no comparison to some of the other O2 Dumps out on the current market place. IMHO there are only 2 companies that produce a nice looking quality made part and JMFab is one of them.

With that said I would like to express what is different about our EPM O2 Dump and the other competitors.

We did some 3-4 months of extensive research and development on an O2 Dump for the stock frame Evo9 Tubrochargers. Our first few prototypes are of similar design to our major competitor. We used a 2.5 inch turbine tube on our first prototype and we Lost power and torque. We tried making the wastegate tube larger thinking that would net us our gains, but again our power gains were minimal; maybe 5 HP. We were devastated, we were sure that an external dump would make big power on these stock frame 9 turbos. So at this point we went back to the design board and started in a completely different direction. We at that point sourced a 3inch turbine tube but with a 5inch CLRadius, and we even tested a 3 inch Turbine tube with 4 inch CLRadius. Both of these configurations proved to be too restrictive. The Turbo exhaust gas slams into the back wall of the O2 Housing and causes way too much turbulence. At this point we man-upped and sourced the dreaded 1DX. In this industry the 1DX is the toughest bend to make. They are very hard on the machine and costly to source. But we at EPM wanted the Best O2 Dump Housing we could make, so we sourced the hard to make, expensive to source; the 3 inch Tube 3 inch CLRadius. Take a look at this picture



You can see just how much smoother our Turbine Tube is compared to our competitors Turbine Tubes. In our EPM design the turbo exhaust flows smoothly around the radius, unlike the competitors that slam into the back of their almost straight tube.
This is what sets us apart from any other O2 Dump Housing competitor. Our turbine tube is more than 40% larger in volume to our competitor. We have countless unbiased factual data logs to show that the EPM O2 Dump housing makes big power. Does it neck down to 2.5 inches, yes it does but so does every other O2 Dump on the market. Know why, because 99% of downpipes made necks down also at that point. For us EPM to manufacture a total 3 inch design we would have had to offer our own downpipe also. That to you the customer would not have been cost prohibited. For us at EPM to in one day make obsolete everyones downpipe would not have been the marketable route to go with. We knew that most everyone wanted to keep their current downpipe so that is the direction we went with our design. We were not redesigning the whole exhaust just one critical aspect of it.
Alastly; there is one other very significant detail that sets EPM apart from all of our other competitors. We at EPM have every step of the way come forward with our test results. We have shown publicly our Data Logs to prove our claims. And other countless customers have come forward of their own accord to show their also impressive but yet unbiased results. We have sold well over 200 units world wide, and our thread on EvoM is I believe the 2nd largest thread on the forums. There is a reason for that.
Thanxx for taking the time to read my rather lengthy post, if anyone has any questions I am available at your disposal.

Now go Dump on somebody--->

 

I have installed 10+ of these and if they leak between the exhaust and the dump tube its cause the customer or shop installed the stock gasket back.. I have done them with copper spray and the gasket they provide and neither leak..

We have run these on 2 of the quickest / fastest stock turbo evo's this season.. they seem to work.. ill work around a fitment issue rather than put a part on that fits but makes less HP..

let me say that i used a competitors part on cwills evo before switching to the EPM and it made less power.. im not the type to mention names so i never said anything and still wont say which companies we used that didnt make the power.. we went 11.1's all day with the car and then switched only the dump and it gave us our 10.98 we wanted..

Mike

 

we use the gaskets that came with them (sprayed on)

im not here to knock someone elses product.. it is good there is more than one solution out there... competition breeds improvements... and people can choose what they think fits their needs.

back on track, we support the JM guys, their products work for us....

Ill continue to recommend to my clients what we feel is the best solution, that doesnt mean everyone else needs to agree with us. for now if someone wants a "noise tube" ill stick to jm's.

cheers

For the record, and as I stated in my earlier post, our product comes with a high quality, high temp gasket that is specifically built for our flange. The initial production run was provided with the copper spray gasket due to the gasket company not having the gaskets made. FWIW, our product, including the gasket, is 100% USA made. By no means am I stating any other competitor's product contains parts from or originates in a foreign country.

so..... mitsu JDM did you get the answer you was lookin for?

that lady on your avatar is hot. whats her name? LOL

 

I would really like to see a comparison. I run the Epm dump. It has outstanding quality and the welds are flawless. Myself and a group of Evo guys stared at it for about 30 minutes admiring the quality of the welds and design. I haven't used jms dump, but I can tell you this:

The Epm does not leak. (unless you had the early version w/ spray gasket and the oem gasket)

It eliminates boost creep

Customer service at Epm is outstanding!

I know everyone on Evo m is biased to what they are fimiliar with, but even if the product touched somewhere, cut the tube! A 2 minute custom fitment solution... Epm has never steered me wrong, and for those running your mouth about facts you dont know, your basing a review off of a company name rather than the r&d.


Keep debating whose product is better, back your arguements up with facts and results not bullsh*t you are pulling outta your rear end

 

^^its obvious whos side your going to take with SPONSORED BY EVO POWER MODS in there sig

I thought this was a JM FAB thread

IMO i was pretty upset with the EPM product seeing that it cost me money about 2+ more hours of labor because there design was not correct as i was one of the first to bring it to there attention that there product did not work with my fpRED because of the J-pipe....Q above you yourself said "We did some 3-4 months of extensive research and development on an O2 Dump for the stock frame Evo9 Tubrochargers."......with all the hard work you guys have put into your product it cost me money oout of my pocket which iam not happy cos now i have a dump with "dents" all over it....

if i had to do it again i would go with JMFAB

 

^

 

doenst ebay racing have a dump pipe already?

 

Its not a JMfab thread because its titled Jmfab.. The OP made statements about other dumps and asked questions as well..

sorry to hear of your issues..

 

This.

 

True but i just thnk JM FAB prducts are overllookd....they build a bad *** stock turbo ex mani as well as a bad *** intake mani...
i know jm well have a order from me for the intake mani soon

 

I was given permission by a moderator to post in this thread, since our products were mentioned.

When at the time of your issues we did not know of your FP extended J Pipe/Turbo outlet. The few problems we have had are because of the wrong version for a specific application. We have exchanged anyone's unit when they ask for it without charge.

I wished you had at the time asked me to work with you on this issue, we would have done everything in our power to make this work for you. Moreover; we were unaware of the FP JPipe setup when you ordered. If you want an exchange for a EPM O2 Dump that is guaranteed to work with the FP JPipe I will more than willing to offer you one free of charge. I thought you were satisfied with the power gains that our product netted you. Also can you take a picture of the dent you speak of that CBRD did to your Wastegate tube, I'd like to see just how severe it is...thnxxx...

Lastly, let's see some results from some of these other O2 Dump Manufacturers. We at EPM are the Only company to go public with all of our data.

 

To make it clear since I've bunched some panties today, got them reporting my posts., and whining to me via PM I am not flaming anyones product. My curiosity got me wondering if there was any transition from the 3" tube to the 2.5" outlet on EPM's o2 housing.

Thanks to those that answered.
