Which Uppipe for 2.0 with EVO III

SacksLax · 11-09-2009, 10:50 PM

So I searched and have been reading for the past three hours. I feel like my stock gutted uppipe is restricting my turbo, and an aftermarket one is in need. Now, I was really interested at the Grimmspeed, but I know it's slightly larger than the others and sometimes larger isn't better since it will cause lower spool, and others may be more efficient to keep the exhaust at velocity. So does anyone have any recommendations for an EVO III 16g 7cm, or 18g on 2.0? Yes it is protuned already. Also what about GS X-Pipe, is it worth it?

My Mods:
SPT Short Ram
Turbo XS Catless DP
Apex'i N-1 CB
APS Inlet
FP EVO III 16g
DW 650cc Injectors
Hyperflow TMIC
Perrin EBCS

I think that is about it for pertinent exhaust and flow upgrades. Anyways, any feedback is welcome. Thanks in advance

Depends on whether you plan on running an external wastegate or an internal one.

I'm going to stick with internal for now

I realize that previous threads for this have been closed. I just want real users feedback on just the 2.0 that's why I put it in here, instead of the newbies. Please don't close. Move if you must, but I really don't see just cause.

Go with a Grimmspeed Up-pipe.

invidia. comes with studs and nice gaskets.

don't do flex uppipe...diameter tapers down to oem or less than oem at the flex.

If you keep what you have or use one hand forged by Jesus, you will net the same HP so you are spinning your wheels.

This is not the case with ours. Our flex section does not taper down.

Ours is not slightly bigger than others. Most up pipes range from 1.8" ID to 2.5" ID. Our ID is 1.92". We feel this is the perfect inner diameter in regards to the size of the oem exhaust manifold and its also not oversized so it won't cause slower spool.

Thanks Justin, I know it tapers to 1.73"?? or something similar. Anyways, I'm going to get the Grimmspeed, for now (soon anyways), and a crosspipe down the road.

I recently searched and found all the old threads regarding this, sorry for making another one, but I also didn't find much on crosspipes. Anyone have any insight to these? I know the factory one is restricted pretty bad around the flex section.

Maybe Jesus makes crosspipes? I live in the Bible Belt, I'll ask around.
