Review: MAP downpipe
I don't think he was having an issue with install. I think he was meaning he hasn't received his yet. Kyle the fabricator missed a few days with being sick and got backed up!
Check your email for a tracking!
Let me know how it goes when you receive it!
Thank you,

The EPM is just an o2 housing, not a complete o2 eliminator downpipe; I like the idea of having 1 less piece to buy. Plus, less flanges/connections means less weight and less restriction. I'll eventually get one and sell my Buschur o2 housing and downpipe combo.
You also run into this with the EPM piece (about a 1/2" of material within the 3" tubing as the outlet flange is only 2.5") which surely can't be helping exhaust flow
You just can't do a full 3" O2 housing on an Evo without redoing the entire path of the O2/downpipe like we have done below.

Any boost creep involved with this piece??? Will this work with just basic bolt ons??? Any other issues besides the 3'' not playing well with the A/C .
I just want to know if they are any downfalls with this piece.

All the guys I know locally with them have zero complaints. No boost creep, no rubbing, nothing. I've helped install the 2.5" version and it went a lot smoother than expected.
I have crazy boost creep with this piece, but I am trying out some solutions next week to resolve.
The piece is otherwise superior in every way to the other dumps on the market, hands down

I sincerely hope you are able to sort out those creep issues sir. I really do feel that the size of the internal wastegate hole is to blame though. I'm not sure what the exact size is on your turbocharger, but the wastegate dump tube utilized on this piece is over 44mm and should have no problem exhausting those gases!
Have over 20 of these pieces in just EvoM Members hands with only one creep issue as shown above. The piping diameter as stated above is over 44mm, this was designed to eliminate boost creep.
