On my last IX my 02 housing I had vent to the atmosphere (Loud, too loud). I have been researching exhausts for my X and I like both the AMS and ETS TBE systems. I am trying to decide between the AMS widemouth downpipe and the ETS split downpipe.

Is there any advantage to venting to the atmosphere?

 

less exhaust pressure through the downpipe. less exhaust pressure = moar powah

 

So for maximum power you would vent to the atmosphere.

Being that it is my DD I think I am going to go for the quieter route.

 

does anyone have a switch for this ?

 

Remove.

 

I've seen the electric cutouts to open up the entire exhaust, but I bet having one to toggle your wastegate from internal to external would be unique and you could have the best of both worlds.

 

Yep. OP search QTP cutouts.

 

A local shop here did just that on a few months back,I think it was a great idea.I have DP with an open dump on my car and love it.

 

Ah very cool, I'm thinking about fabbing up a pipe that I can attach to my ATP Downpipe with external wastegate. Right now it's re-routed into the downpipe but for racing it would be fun to be able to swap an external dump tube in there. I can just rotate the external wg a bit and attach the piece, then cap off the downpipe for a 5-10 min swap that gives a bit of hp and sounds really mean.

 

isnt there mini mufflers people sometimes put on these to deaden the sound.

 

They have many mufflers for the setup, but we have never tried them. We recommend the recirculated downpipe for daily drivers that don't want to be noticed under boost. If you want to vent to atmosphere you WILL be heard at WOT.

We like to separate the wastegate gases from the turbine gases to create a smooth flowing exhaust and less turbulence.

Does the ETS downpipe fit RHD EVO X? (I'm looking for one and I know that the AMS widemouth doesn't.)

Michael can you chime in?

Regards.

 

Honestly - I'm not sure. We have sold a couple overseas but I have never received feedback, so maybe? The answer is I dunno

Thanks,

Michael

 

ETS Open dump!!! You won't be sorry!

 

Ricer with the VTA.
