Chronuss Posted June 2, 2015 Share Posted June 2, 2015 I know this is an old thread, and I've searched...and searched, and searched a third time, but I would like to find a part number, and, or, a link to an up pipe for a 5EAT, or if anyone can PM me some info, that would be amazing.

zj egg Posted June 2, 2015 Share Posted June 2, 2015 Uppipe is the same for manual or automatic. downpipe is the one to look out for Link to comment Share on other sites More sharing options...

fstaslp Posted July 2, 2015 Share Posted July 2, 2015 What pins does the resistor plug into? Link to comment Share on other sites More sharing options...
DrD123 Posted July 3, 2015 Share Posted July 3, 2015 when you unplug the temperature sensor that is in the OEM up-pipe, you put it across those two terminals on the engine harness (the factory sensor is a thermistor, so you are basically providing a resistance that makes the ECU think all is well with the catalytic converter in the up-pipe - without the resistor you'll throw a code) - when I did this on my WRX, I took apart the connector to the sensor on the up-pipe, soldered the resistor between the two pins, then filled the end of the connector with sealant and plugged the connector back into the engine harness - looks a little cleaner than electrical tape, but both approaches will get the job done.

covertrussian Posted July 7, 2015 Author Share Posted July 7, 2015 The best solution is to disable the codes with the reflash. The resistor that is suggested everywhere makes the ECU think EGT's are at 1292F, which has thrown a cell for me at times on the highway. I think using a different kohm resistor to make the ECU think it's around 700F would be best. But with Radio shack closed and with it being easier just to reflash I stopped searching for another way to skin this cat. 05 LGT 16G 14psi 290whp/30mpg (SOLD) 12 OBP Stock 130whp/27mpg@87 Oct 00 G20t GT28r 10psi 250whp/36mpg 22 Ascent STOCK Link to comment Share on other sites More sharing options...
Shogun506 Posted August 15, 2015 Share Posted August 15, 2015 Why is the downpipe removed during this install? I see it in all the instruction videos Link to comment Share on other sites More sharing options...
covertrussian Posted August 15, 2015 Author Share Posted August 15, 2015 There are two nuts that are very hard, if not impossible, to reach with the downpipe there. Those two nuts are right behind the turbo (I think I have a picture of it in the first posts). 05 LGT 16G 14psi 290whp/30mpg (SOLD) 12 OBP Stock 130whp/27mpg@87 Oct 00 G20t GT28r 10psi 250whp/36mpg 22 Ascent STOCK Link to comment Share on other sites More sharing options...
Max Capacity Posted August 15, 2015 Share Posted August 15, 2015 (edited) http://i185.photobucket.com/albums/x40/92Si/DSCN4782.jpg That would be the bracket that holds the up pipe to the block.

covertrussian Posted August 16, 2015 Author Share Posted August 16, 2015 Here you go, these two nuts are the ones that you can't get to unless you drop the downpipe. http://i160.photobucket.com/albums/t188/covertrussian/Cars/05%20LGT/Engine/Exhaust/Uppipe/CIMG9694.jpg 05 LGT 16G 14psi 290whp/30mpg (SOLD) 12 OBP Stock 130whp/27mpg@87 Oct 00 G20t GT28r 10psi 250whp/36mpg 22 Ascent STOCK Link to comment Share on other sites More sharing options...

AviMoore Posted December 7, 2015 Share Posted December 7, 2015 Awesome write up, gives a good idea of the work required. Considering doing this on my 2005 LGT. Since my car is stock otherwise and this is quite a bit more flow than the catted pipe, do you think its safe to just run this pipe without any tune?

You Do Not need a tune for A catless up pipe, running it without a tune will not harm anything in any way. Even without a tune you should notice just a little extra torque.

Max Capacity Posted May 30, 2016 Share Posted May 30, 2016 Correct, all the tune will do is delete the CEL for the missing egt probe. Or just stick in the 2.2k ohm resister. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

Hunny_wagon Posted January 16, 2018 Share Posted January 16, 2018 Anyways.... I just replaced my uppipe last weekend and had used THERMOTEC heat wrap on the uppipe and the manifolds since I had them off. A week later I'm still getting a burning smell from the wrap. If anyone else has used the heat wrap, does the burning smell go away? Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Max Capacity Posted February 6, 2018 Share Posted February 6, 2018 For those viewing this before doing this job you should think about replacing the oil return hose from the turbo while your there and remove the banjo filter on the back of the head. You'll notice I chose to bolt the turbo to the up pipe in my pictures. Makes it easier to line things thing's up like the inlet tube, oil return hose and up pipe at the same time if the turbo was removed. I also left the three turbo to up pipe bolts loose so you have a little more play when trying to line up the stock style tmic. After the tmic is in place then tighten every thing up. Again use anti-seize compound on all threads. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

zmadanat Posted June 9, 2019 Share Posted June 9, 2019 Thanks for the writeup. I did this and now that my Invidia DP is in I'm going to be throwing that on soon too. Link to comment Share on other sites More sharing options...
GearJamr Posted October 7, 2021 Share Posted October 7, 2021 Is it absolutely necessary to remove the headers? The repair manual for the "joint pipe" shows just removing the RH manifold cover. I'm looking at doing this when I do my turbo back and want to save as much time as possible. And if I'm taking the headers off then I'm just gonna replace them.

xt2005bonbon Posted October 7, 2021 Share Posted October 7, 2021 Taking the header off is actually pretty quick: 6 bolts and the whole thing comes off. (well after removing a few heatshields that is...) IIRC, you do not have to remove it in order to remove the uppipe. It is a tight squeeze but it should be possible. It's been a long time though... This reminds me I need to replace my Invidia cracked up pipe. Trying to find a 'cheap' alternative.. Link to comment Share on other sites More sharing options...

I'm also in Utah, but northern, so shipping would be cheap. It's free if you're interested Sent from my HD1925 using Tapatalk Link to comment Share on other sites More sharing options...
