The downpipe install on the X is tedious. A lot of the cheaper parts have fitment issues due to poor quality control. I would be careful on parts like this.

If you get a chance.

Check out our site.

we have 2 downpipes to choose from.

1.) Recirculated Downpipe

2.) Atmosphere Dump Downpipe.

Both will net similar results on the stock turbocharger. The Atmosphere dump downpipe will be considerably louder under wide open throttle conditions.

If you have any questions, let me know!

Thanks,

Get ETS or ams

 

thanks Michael and i am looking at ETS, just need to figure out if i need Recirculated or Atmosphere

 

Do you want to be super loud at WOT? If yes, buy atmosphere (aka open dump, o2 dump, etc)
At normal cruising throttle, it'll be similar as recirculating downpipe.

I believe it's all to help the exhaust gases create less turbulence when exiting through the exhaust system and wastegate. I don't know the technical details about it or if it makes a major difference. I'm an Evo newbie myself, so take that with a grain of salt.

EDIT: Here's a helpful thread. https://www.evolutionm.net/forums/ev...circulate.html

 

i dont really want the car to be that loud, , i have the ETS UICP on it right now, looking at ETS intake, maybe intercooler, so this is for now, and DP once i figure wich one i need, are both same performance? i also have a boost gauge i need to instal and A/F. i understand the basic of each dp just not sure wich one to get, also planning on stock turbo for now..sorry guys still learnight this Evo stuff

 

That's exactly correct. It is also why, if you stay with a system where the exhaust going through the wastegate ends up in the main system, the longer the tube on the wastegate, the better.

The only other issue to mention is whether you ever do something like autocross. Even in the "highest" classes (e.g., Street Mod in SCCA), none of the exhaust can be dumped under the car.

 

no motorcross nothing like that..just my DD...this stuff is confusing...

 

I would get the recirculated downpipe. No crazy increase in noise and you won't have any problems at the track or road coarse due to noise levels.

thanks Michael... i see you have a phone # here, i will call you if you dont mind, i have few other question..thanks for help guys
