Default Up Pipe Install Disaster

Yesterday i took my car to a shop to have the Grimspeed up pipe replaced because it rusted through the flex and had a huge exhaust leak.. I bought the exact same pipe ( 2 bolt with 38mm external waste gate) The shop i took it to worked on it for 7-8 hours. They said that it was not matching up well with my current set up which is an Invidia down pipe and Tial wastegate. They say the car had a few seized bolts and had to be replaced. The O2Sensor would not screw back in tight so i assume it is barely in there. Honestly i'm not sure what to think about the install it seems to be ok, but just needed to put this out there in hopes to receive some positive feedback or things i should watch for now that its over.

It sounds like they got the pipe itself installed. I would check all hardware is installed and tight. Check and make sure the o2 sensor is fully seated against the washer. If the 02 sensors are stripped or too corroded they may not tighten and will need to be replaced. Be careful, if they stripped the sensor it may have stripped your uppipe.

Give it a check and fix it needed, hopefully they didnt strip it.

Hard to tell exactly what went wrong. A little anti-seize always works well when installing an O2 sensor. While the fit might be a little off, it does eventually bolt back up no problem. If you had the same DP and EWG prior to the swap, then the only hiccup could be from the seized bolts probably. But the Uppipe bolts to the Exhaust Manifold and the Turbo, not sure how the DP came into question.

Do you know if they used new gaskets? If it has been awhile, it is always best to replace the exhaust gaskets for each connection broken up.

I never want to see a thread title with our name and "install disaster." However, it looks as if there wasn't a problem with the pipe itself, but rather the installation. An external wastegate uppipe install on a car with non-seized hardware takes me around an hour to two hours from start to finish. I could see that time increasing when they start having problems with studs or bolts, especially ones at the turbo. Breaking a stud at the turbo means the turbo is coming out, which sometimes happens and will add a lot of time to an install.

As far as the uppipe not matching up well with the downpipe and wastegate, this is a harder pill to swallow. The 5 bolt flange of the uppipe bolts to the inlet of the turbine, which has a location that is dictated by the two mounts bolted to the engine. If these mounts don't move, then the turbo doesn't move. If the turbo doesn't move, the installation of the downpipe is completely unaffected. The wastegate fitment is the least constrained and shouldnt be affected by anything on the install as the is clearance between the downpipe and wastegate.

It kind of just sounds like they were having a hard time as opposed to there being a disaster with our uppipe. If this is not the case please let me know and I can help you out.

I agree this wasn't on Grimmspeed. I didn't mean for it to look like i was calling out Grimmspeed for my mess of a install. The Grimmspeed pipe is a quality product. I ran the car this weekend and it seems like its put back together well. I still need to stick my head under the car to check all bolts.
I was just a little concerned after the install because 8 hours just seems insane... seized bolts or not.

ALso u would make sure that there is no added stress on the flex pipe or that will become the breaking point due to stress.
