great product! 5 years ago
Many people say you wont notice a difference over stock. Maybe if the rest of your car is stock but if already modified, it makes a huge difference in spool time. Running a 20g with full header and exhaust swap, this was my last piece to change and it lowered my full spool by several hundred rpm. Also, ive done a turbo swap since amd with the pesky heat shields gone, the oil return butterfly clip is easily accessable.

Grimm Speed gaskets 6 years ago
Very High quality gaskets. Had originally bought the one gasket to deal with a leak and ended up doing the complete exhaust system just for the hell of it with these great gaskets.

Great leak free seal!!! 7 years ago
I bought this gasket to install up grimmspeed uppipe and it worked great. It is a very thick gasket and looks be made very well. I just installed the gasket and tightened down the bolts to torque spec and No leaks. Great gasket all around and would def buy again.

First review of GS uppipe gasket 7 years ago
The Grimmspeed up pipe gasket is slightly thicker with more layers than an OEM gasket. The price is comparable so it was worth a shot. I have other GS products on my car and have only great things to say about them. I have an aftermarket up pipe that seems to start leaking in the fall every year. I am not sure if its temperature related, but since I have owned the car its a regular process to replace this gasket once the leaves start to fall to alleviate the whistling sound and low boost pressure. Time will tell if this gasket holds better than the OEM or pure copper gaskets I have used in the past. I will attempt to write another review next year if this gasket holds up over time.

Quality is top of the line, and the price was good, I would use a Grimmspeed gasket on my car without hesitation

Gets The Job Done 8 years ago
I would definitely use the grimmspeed gasket over the oem one. Grimmspeed's gaskets are slightly thicker, so if there happens to be a small amount of warpage the gasket can make up for it and you will be leak-free. This is especially important pre-turbo, because turbo response and spool will be effected negatively by exhaust leaks.

Good Gasket 8 years ago
Fitment was great and the gasket is holding up fine so far. I think the GS gaskets are a little cheaper than Subaru ones too but the quality is the same or better.
