Default Anyone had problems with grimmspeed downpipe fitment?

I wanted to start a thread asking this in a more relevant forum but couldn't find a better one. If you know which is better suited, please mention.

I'm not attempting to make the guys at grimmspeed seem incompetent or unhelpful, but their suggestion just doesn't seem logical and didn't work. They were very courteous and helpful when I needed to get the downpipe from them since an ebay seller sold me one part number then sent the incorrect one because they claimed "grimmspeed no longer offers the 007001 so this is the replacement". :/

I recently received a grimmspeed 007001 limited downpipe and purchased a cheap SRS SE catback at the same time. Initially, neither the catback or the downpipe lined up where they were supposed to be.

The catback needed to be further to the driver (left) side of the tunnel to hang on the center hanger. The downpipe was way over to the passenger (right) side of the tunnel and there was no way they could bolt up and "pull" things together.

With the catback hanging correctly in its hangers, this is where its flange was in the tunnel... centered. You can also see the downpipe flange was off to the passenger side also preventing the rear mounting tab from even being close to the transmission bracket.




I was told by grimmspeed that I would need to loosen the vband on my killerb uppipe and the bolts on the turbo and its brackets to rotate it so the downpipe would move. This did not work as the brackets and the uppipe were precisely located and the holes weren't large enough to allow the turbo to move much. You can also see the vband for the uppipe is practically vertical, in a completely different plane of rotation from what I needed to happen. Even if you do try to rotate the uppipe, the two turbo to engine / uppipe to engine brackets will prevent it. Tightening those two brackets to the uppipe will only pull both sides of the uppipe back into original position. Someone has to understand what I'm trying to explain and I don't have a way to draw it out and illustrate. Here is the almost vertical vband flange:

Well crap, I can't add it in apparently so I will add the pic in the next post. :/








I still tried holding the turbo one way while tightening the bolts...didn't help. What I ended up doing was just rotating the downpipe with the upper downpipe flange bolts loose, it seems the holes are kind of large so it twisted enough to move the pipe over some. It wasn't quite centered but close, then I connected a wire to temporarily hold the lower end to the transmission. You can see its fairly centered in the tunnel but its just odd that I had to try all kinds of tweaking to get it there.


/\ notice also the leak free seal allowing water to drip out likely due to the catback flange not lining up with the grimmspeed gasket. I really wish both companies would have made the holes the same size as the bolts they provide or provide larger bolts. I will be buying larger diameter bolts so the gaskets and the flanges will center and seal better either way.



I didn't have this issue with my cheapo downpipe and would have posted a pic of it but for a while I've had that previous exhaust welded into one piece to eliminate the cheap leaky flanges and add resonators, electric cutout, etc and its a real pita to reinstall that beast. Besides, showing a picture of it lining up correctly wouldn't prove anything, surely someone would say the modifications I've done are the reason for the good fitment.
Just seem like for the price it should have sat in the correct place without any addition caressing or "tweaking" from the installer. Again, I'm not saying the downpipe has to be off, but if there is something else that is more likely tweaked I'm open to another suggestion.

I'm going to mention the details of my setup so someone can jump in and conclude that is the problem and I'm wasting time posting. Luckily a few people are blocked so when they post I don't get to see their snotty remarks.

I sent the downpipe back to Grimmspeed so they could check it on their weld jig and was told everything lines up perfectly. They even sent photos of it bolted to the jig. They told me a new downpipe would fit exactly like mine does and are willing to refund me for the downpipe.

The problem is that I've replaced the up pipe brackets and the transmission crossmember and I have oem group n engine and transmission mounts keeping everything straight. The killerb header and uppipe line up perfectly to the brackets so the engine and trans side of the equation fit. I've taken several pictures that show everything being way off, but without the guys at grimmspeed being able to actually see it in person I understand how they could have doubts. They have also made comments as to my car being "hybrid" and that tends to make me believe they think its something to do with that.

I finally found an oem 05sti downpipe locally and was able to install it with zero problems. The rear bracket on the pipe was easy to get into the trans hanger bracket and the rear flange centered in the tunnel as oem. This is with a 2011 transmission and 02-07 hanger bracket, so yeah subaru does keep certain reference points exactly the same from 93-2007. I did not have to pry, bend, coherse, "massage" or do anything else to get thie oem pipe to go in. I am confounded as to how this is possible, since no one else has mentioned fitment issues with theirs. If I knew there was a problem with my drivetrain alignment I would definitely take care of it, I just have a problem with installing something I don't know for a fact is precisely aligned as it should be.






...and a pic of my rigged connection, had to cut/shorten the springs to rig it so I could at least run the car while waiting on downpipe results. It doesn't seal perfectly, but obviously the catback isn't designed to run with the oem donut. This connection lined up with no effort. I didn't have to pry anything or force the flanges to align.






post continued because not enough pic room.......

I'm sure its just a bad perspective (and obviously not an accurate way to measure a part ) , but even in this pic it seems the GS pipe veers back to the passenger side past the trans bracket


There is NO way these two parts will align, the GS pipe is not flexible in any way shape or form. These pics are after loosening the upper flange bolts and tweaking the pipe all the way over to TRY and get it close, it is not moving any closer. You may think it is possible, but trying to push that pipe towards the bracket basically tries to force the turbo/engine/transmission upward....not happening.






New oem brackets from a subaru dealer, notice how the uppipe is aligned:

Grimmspeed sent pics of my pipe mounted in a jig. I replied asking for them to send pics of my pipe installed in a 2002-2007 wrx, mounted to the oem hanger bracket and connected to the catback. If they can do this, I have no idea how my setup is off. I should probably just get the refund and try another pipe. Either way, I will post a pic here "if" the new downpipe fits/aligns as it should.

They weren't able to get any pics of mine mounted on an actual car, they sent me a couple of pics of an employee's car with the same type of pipe and oem catback. They did process the refund though, which is good. I have another downpipe on the way and hopefully it fits. If it doesn't, it will be time to find someone good with welding stainless. :/





I made a video of the entire exhaust, with the car running. Try to ignore the engine noise, its a cold start and the JE pistons are not as loud as the camera makes them sound.

My buddy has one on his car and fitment was spot on.. I know that doesn't really help you out much but I'm interested to see what happens with the new downpipe.

Thanks for the reply, I have no doubt they fit well on many cars and yes the guys at Grimmspeed are very professional and they try to help if possible.

The lack of more replies leads me to believe either no one ever has fitment problems or no one feels like replying. I have an Invidia on the way and supposedly they are also good about fitment. If the Invidia is off, at least I won't feel as bad about modifying anything. The Grimmspeed is such a good looking part, it would pain me to cut it. Its just amazing to me I couldn't get it to come close, I have no doubt the header is exact....it even lines up with the uppipe brackets on its own. I didn't have to adjust the brackets or try and wiggle the uppipe. Something has to be off, but the oem pipe fits so well it has me baffled. Apparently logic doesn't apply to my car. I even thought the aftermarket turbo may have been off, but swapping it to the original vf22 didn't help.

Good news for me, the Invidia fit great!

Installed and the car running:





rear flanges stayed aligned with no bolts... centered in the tunnel








Grimmspeed does have a great return policy, but apparently something isn't adding up on their end.

1-Oem downpipe lined up perfectly, no issues

2-Invidia downpipe lines up perfectly, no issues

3-Grimmspeed 02-07 downpipe wasn't close...yet it fit perfectly in their jig

-The guys at grimmspeed installed my pipe in their jig, and I was told several people looked at it and it fit perfectly. They even sent a pic of it sitting in a jig. I requested they install my pipe on a 2002-2007 wrx to verify fit and they did not. They did show me a pic of an employee's car with the same part number pipe on it which led me to believe they knew it couldn't be and issue with my pipe and there was no point mounting mine.

It seemed to me that they believed something was wrong on my end and it couldn't be the pipe. They even mentioned my car being a "hybrid" setup which bothered me and also makes me believe they were over confident it was a problem caused by me using different year model parts.

I bought the GS pipe because I totally believed it was the best pipe on the market. It had the wastegate design I wanted, it had the thick flanges I wanted, and it had the american brand name I thought I wanted. I went through ten kinds of bs trying to find out what was "wrong" on my end. NOTHING was wrong on my end. My time was more than wasted, and that is what aggravates me the most. Its NOT the money I spent on the crossmember or the uppipe brackets, its not the fact that the GS pipe cost basically double what other pipes cost... its the time wasted for nothing.


I'm sad to say that will be the last thing I buy from them.

I feel like they did everything they could to help you. Do you think you would have the same customer service if your Invidia pipe didn't fit right? Grimmspeed is a great company with the best customer service I've ever dealt with.

I will be a Grimmspeed customer for life.

You feel that way because you got a good part, I on the other hand did not. If you had gone through the bs and spent the money I did to figure it out on your own you may feel otherwise. I know the majority are going to come in and post how perfect their parts fit and how no one they know has ever had problems with their products. I also understand chances of someone who's had a problem and actually notice my thread are slim, especially since GS usually will warranty their parts. I would think however that SOMEONE would notice what I wen through to try and keep their frigging pipe and realize it would be totally illogical to think my concern has no merit. I would hope all of the photo and video evidence and my time wasted weren't for nothing. :/o

I'm not sure you noticed all of my above post so I will repeat that the catback seller sent me a brand new catback to check fitment, then paid to have it returned. They allowed me to keep the original catback so I wouldn't be without one. I would consider that great customer service, they went beyond what they needed to do to show they appreciated my business. I actually had to buy another downpipe (oem that fit perfectly) while Grimmspeed was checking mine on their jig. They did not offer to send a new part, they needed to see it for themselves first. Too bad there was no way I could have tried it on a local wrx before sending it to them.

Default bump old htread but I have exact same issue!

Mine has the same out of whack trans mount, but my pipe end points to heaven and so it won't sit flush with exhaust and leaks bad even with grimms thick gasket. I mean like a 1/4 inch so it's not possible to tweak or maneuver in at all! I am calling them to see what can be done when they open on Monday. My turbo wastegate also hit the separator and couldn't even get downpipe in. I bent the flange out of the way so it could be installed but that doesn't seem like a good fix. I am not sure my wastegate flapper is opening all the way either, but no way to see when it's installed. My downpipe seems short also, this has been a nightmare.

Post some pics in this thread if you can

(Maybe it's my old pipe :/ )

I'm sure they will warranty it for you, but it's doubtful they will admit fault. Even after installing an oem wrx sti downpipe and new Invidia downpipe and showing (with several pictures and video) fitment being perfect, they never admitted or apologized, and that is why I can't buy anything else from them. I even regret buying some of their shirts.


I now have a 2011sti transmission and rear diff (it was a 2011wrx trans and diff before) and the Invidia fits EXACTLY the same as before, nothing with the geometry has changed. I bought several parts including new turbo brackets and another crossmember trying to see if the problem was on my end, and it WASN'T. I didn't expect money for buying those parts, but an apology and admitting the problem was with their part would have sufficed. They even told me my downpipe fit their vehicle perfectly..yeah, ok.

Even the ebay company who sold me the chinese catback exhaust allowed me to exchange it during this fiasco, to see if another would fit differently and it didn't. The time wasted was one of the things I will always remember, that won't be happening again if I can help it.
