ETS vs. AMS
Nothing JDM makes better power then ETS, AMS, or Buschur.
JDM=just double the money. Nothing else good about JDM parts.
We do it better.

AMS is only 25 minutes away from me so I tend to lean towards them. Don't have any ETS goodies on my car so can't speak about them.
I love the parts I have from AMS even though I had to pay more for them. They fit really well, in most cases better than stock and the R&D that goes into them pays off too.

I have ETS TBE and I love it. there are minimal bends and it sounds badass. That and the fact that they have an anodization option for their intercoolers lead me to buy one of their gold intercoolers. its probably not everyones cup of tea but its baller fa sho and im more then happy with the gains. Dont have any experience with AMS, but im nothing but happy with ETS
And they are not sold at auto zone.
A few of my ETS goodies
The reason for splitting the wastegate gasses from the exhaust gases is to prevent any excess turbulence. When the wastegate opens and closes it draws air backwards and interrupts the exhaust flow. By separating the gasses it allows for a smooth exhaust flow with no excess turbulence.
We have a nifty little drawing that was done in fluid dynamics to show the flow patterns of our downpipe.
If you have a wastegate opening and closing you would see the interrupt in flow, but by having it separated it flows perfectly.
Thanks!

Our downpipe has been proven over the wide mouth design by several reputable sources. Mike @ AWD has made more power with our downpipe then any other downpipe on the market for the X.

Can you explain what you said here further
Quoted form above : "When the wastegate opens and closes it draws air backwards and interrupts the exhaust flow."?
Also the EVO X turbine housing already has a divider wall built in between the turbine exit and the WG port. The only time this could affect anything, (and it would be a very minor affect at that) is if this divider wall would not be there and the WG port exit was shooting directly into the turbine exit stream.
-Martin Musial
The reason for separating the wastegate gasses from the exhaust gasses is to have non interrupted flow or excess turbulence when the wastegate gasses enter the exhaust stream. By having a separate dump tube for the wastegate gasses this guarantees smooth exhaust flow and by the time the wastegate gasses reach the exhaust steam they will have an established flow pattern.
The Evolution X exhaust manifold does have a divider build into it, but the wastegate is not open 100% of the time or between shifts this is where the interrupted flow will take place.
Granted this may be a minor difference, but we have had several shops report higher horsepower gains using a divided downpipe vs a bell mouth style downpipe.
Thanks,
Michael
