The OVERTAKE Exhaust Manifold to Head Gasket seals the exhaust manifold to the cylinder head on the H6 Subaru using multi-layer steel construction with a stainless steel fire ring. If you run an EZ30 or EZ36, you have probably found out that Subaru no longer sells this gasket, and the budget aftermarket versions that filled the gap do not hold up.
The original OEM gasket sat in a hot, high-pressure spot and did its job, but Subaru discontinued it (44011AG040). What is left on the shelf is mostly thin, stamped material that is not fully stainless, which is where the dreaded waffle-gasket blowout comes from. The OVERTAKE Exhaust Manifold to Head Gasket is built for the Subaru H6 the way this joint should be sealed, covering the 2004-2009 Outback through the later Legacy and Tribeca. Multi-layer steel, a stainless fire ring, real thickness, and it comes as a pair so both heads get done at once.
WHAT WE SOLVED:
With the OEM part gone and the cheap stuff failing, this is the gasket that actually seals and stays sealed:
- Direct OEM replacement, no longer available new
- Full stainless multi-layer build
- No more waffle-gasket blowouts
- Survives real heat cycling and pressure
- Sold as a pair for both heads
FEATURES:
- Multi-layer steel construction with a stainless steel fire ring at the combustion seal
- 22% thicker than the original OEM gasket for a more durable, longer-lasting seal
- Fully stainless build where many aftermarket gaskets use thinner, non-stainless material and fail early
- Engineered specifically for the Subaru H6 exhaust system for a reliable, leak-free fit
- Sold as a pair to seal both cylinder heads
- Direct replacement for the discontinued OEM Subaru gasket 44011AG040
THE DETAILS:
The exhaust manifold gasket on the H6 Subaru sits in one of the hottest, highest-pressure spots on the engine. Subaru no longer supplies the original, and the aftermarket options that stepped in are mostly thin stamped gaskets that are not fully stainless, which is exactly where the waffle-gasket blowout comes from. The OVERTAKE gasket is built the way this joint should be sealed, with multiple layers of steel and a stainless fire ring around the port, running 22% thicker so it holds clamping load and takes the pressure a tuned car makes. It drops in as a direct replacement for the discontinued OEM part 44011AG040 with no modification, and it comes as a pair so both heads get done in one job. It also carries over to H6 swap builds, where a gasket that can take abuse matters even more.

Great quality / product. Just got the wrong size for the gasket. I believe I need a 2.5 inch diameter gasket for my Cobb downpipe.
Another nice gasket set from Overtake. The intercooler inlet gaskets are good quality, nice and thick, and fit perfectly on my 2003 WRX. Great replacement for the old gaskets, especially when you already have the intercooler off and want to make sure everything is sealed up properly when it goes back together.
Nice quality gasket. It’s thick, well made, and fit my 2003 WRX intercooler BPV perfectly. Compared it with the OEM gasket and the fit was right on. Definitely a good replacement if you’re taking the intercooler or BPV apart and want to make sure everything seals back up properly.
Arrived just in the time it said it was and it fits perfectly! The reason I ordered it is because I asked a question and they responded with an answer asap! Customer service is where it counts!
I highly recommend the overtake 2.25-2.5 inch axleback gaskets to replace all those composite gaskets because the overtake gaskets are MLS and they work we better and you don’t have to worry about them blowing out.
Good quality, definitely will use for all my cars
The gasket is larger then the OEM one so should let more air though.
Thank you so much for your team to helping me out to pick the right gasket for my 2017 subaru wrx sti...
Very nice quality parts, fast shipping.
Great gaskets, nicer than OEM.
This is a must get product..helps eliminate exhaust leak material is phenomenal. Well made.
Got a new downpipe, so a gasket was needed, and this thing is way more durable than OEM. The quality is on point!! 👌 thanks again Overtake for a good product!!
Very good gaskets that are super thick & for high-performance aftermarket headers & EXHAUSTS. If you have a leak, highly recommend this part will fix it 10/10 thx you (overtakeusa)
Top of the line gaskets that are super thick!!! highly recommend them! Check them out at overtakeusa.com
Wifes STI needed pretty much every exhaust gasket. These fit with the Invidia cat-back 2.5" exhaust sections!
Great quality and amazing packaging

Great experience! Art walked me through everything, gave me some advice without being pushy about trying to sell me more. Definitely my best experience at subifest Midwest.
Quality gaskets was surprised how thick the manifold gaskets were. These came up in Google Ai for recommendation and i see why now.
Great product worked as it should would buy agin to fix my leaky exhaust
Way thicker and better material than oem gaskets. When I need a gasket quick I order from these guys!
My car eats gaskets. So everytime I have to replace it this donut is always in great shape.
