Hey guy, so my RAD will be here very shortly and i am curious to know what downpipes used in conjunction with this turbo would net the most power. I want to install the downpipe the same time i swap the turbo but dont know which one to get. I've been lookin at the UR downpipe. Any comment or suggestions? And please no comments about just getting an X turbo. I already thought of that, but decided to go the RAD route. Thanks guys!

 

The UR Long DP is the best route for the RAD turbo, or u can go with the short pipe. I have a UR short DP if ur intrested.

 

ur long downpipe would be the one that i would get

 

What are typical gains with the UR long downpipe?

 

I have the UR long downpipe, and im happy with it, after installation i felt that spool was little faster. I might be selling mine soon since i will be doing turbo swap.

 

Any 3" downpipe will really work. Even the Rad Lite won't flow enough to even come to the capacity of anything 3". Really you could go with any downpipe at 3" diameter, have the stock O2 housing elbow thingy ported to flow a bit better for that new turbo and you should be good.

 

Any input on the ease of install on a short vs long downpipe? There's not really any input from anybody besides people saying the long downpipe takes 5 hours+ to do. Or should I just let Boostin performance mess around with it?

 

Well the short is easy to install but if ur switching out turbo then do the long one, they have to remove the o2 housing and it will be easy to install the long at that time.

 

Pm me when you wanna sell it. Im gunna hold off on installing my rad until i acquire a few more parts to install all in one day.

 

Since your installing a new turbo anyways. UR long pipe for good power, AMS wide mouth for the most power. If not, just find a stock evo x downpipe for 20 bucks and use that. Either way, the downpipe install is going to be part of the entire turbo install.

 

???? AMS ad Evo X DP does not work on the Rad Turbo or the OEM ralliart Turbo. You only have UR short pipe or long pipe as ur options. If ur upgrading to a rad I recommend doing a UR long pipe.

 

Oh my bad, I thought it was turbine upgrade. It's just a compressor wheel.
I thought all evo x short downpipes work with the ralliart and the O2 housing would have to be dedicated to the RA. Sorry about that.

 

No worries :-) but yes all Evo X short pipe will work for the ralliart. If doing that then just get the UR 3" DP so u can save for other parts. AMS makes a long DP which is really nice. I have it in my car right now as I have the Evo X setup.
