grimmspeed 38mm ewg uppipe review
hello everyone today im reviewing the grimmspeed 38mm ewg uppipe.
the uppipe is coated from grimmspeed and the coating appears to be very good. we will see though how well it holds up to the heat overtime.i gotta say i love the thick flanges on this pipe.construction is top notch as are the welds and the inside of the pipe is nice and smooth.definetly what youd expect from grimmspeed. id also like to comment how its very nice to be able to buy a readily available up pipe that has the flange for a ewg rather then having to mod a stock or aftermarket up pipe i think its just great im also going to enjoy this ewg set up alot because on the outside my car looks completely stock with my beat up wheels and everything haha im going to enjoy this i had the stock sti pipe in before so hopefully with the new uppipe and the tial external wastegate ill see some nice gains! install done one 2/28/13 the install of the uppipe was very easy i went from the top though as i had my turbo out anyways for my inspection. overall it will be easier to install this vs stock as it doesnt have gobs of heat shield around it,so it should slide in nice and easy. i gotta go back to the topic of the flanges again they are nice and thick wich i think helps alot with gasket sealing makes everything tight i love it. also the position of the ewg flange is great,im pretty convinced this uppipe will fit with any down pipe,currently i have a cnt downpipe, and that cat is right after the bell mouth and that fith with the ewg and dump tube its just freaking great,grimmspeed has a good thing going with these uppipes and there support of the subaru community i hope they continue to support us and continue to release new and exciting products. i just want to thank everyone at grimmspeed for giving me my perfect solution you guys are great.

Yeah it's going to depend on the size of the turbo and how much boost you're looking to make
Here is a great article on sizing WG's http://www.dragzine.com/tech-stories...nd-wastegates/ Mike |

i was dissapointed in grimm speed. i wanted a coated 44mm uppipe and they were at the coaters for way too long. so i had to settle with a uncoated uppipe. still a great product just a lil upset its not the coated version.
but everything else is good for grimmspeed. also i perfer the 44mm for a smaller turbo on big boost. rally guys use 2 wastegates on small turbos all the time. you can get the fast spool of a lil turbo when the ewg is closed. but as soon as it opens your turbo breaths alot better on exhaust side. its the key to a hybrid turbo. if you have a super small exhaust side and a big compressor a big wastegate is ideal. it helps get rid of the pressure in the exhaust side. which is the lil turboz down fall. https://www.youtube.com/watch?featur...5T5PnWE-k#t=14 |

Thanks for sharing! We're glad you're enjoying it! Quote:
I should note that we do all of our coating in house. Did you order your part through us or a vendor of ours? If it was from a vendor chances are they just didn't have the part in stock or on order. Mike |

i ordered my uppipe from turbo tek tuning. they had a uncoated one in stock
after the install my well known subaru mechanic noticed a leak near the turbo. he thinks its the upipipe. i said it couldnt be with it being a more expensive grimmspeed brand. sure enough i have the same problem as this guy..... http://forums.nasioc.com/forums/show....php?t=2205000 so i am asking grimmspeed for a full refund and i want a turboxs up pipe |

With that being said, even a flat flange can leak. Not necesarrily due to the flange, but the order in which all the interacting parts and peices are fitted together and bolted up. There is a right and a wrong sequence in tightening things down. In the end, if you are having any issues with our products give us a call, we will make sure things get sorted out. 612.379.0000 -Matt Homes |

If you have the 38mm Tial MV-S and with the Grimmspeed up pipe, the install is tricky. At first, it seems like the vband for the up pipe connection is too narrow.
In order for the vband to fit the flanges you have to press it together really hard. This is because the recess on the up pipe flange isn't deep enough to accommodate the valve seat under pressure. This isn't a Tial issue. I actually installed mine with the spring out and had a F*** of a time getting it compressed while attached to the up pipe. DO NOT attempt this! Also, gs told me to remove the valve seat but I couldn't figure out how to and my tuner advised against it. GS, love your product it's great but maybe consider deepening that seat a little thanks. |

My flex joint developed a hole in it. I just sent them an email.
You replaced yours with the same pipe again^? Any issues since? The flex joint has me nervous now...... |

what wastegate are you running? i had a hell of a time clamping my tial mvs to the flange. its like the flange on the upipe was too thick almost because the tial flange would go in the v band clamp with the wastgate very easily.
