"Grimmspeed delivers as usual!"
100% Thicker than OEM Gaskets!!
Our new 2X Thick 3" 2-Bolt gasket is hands down the most beefy 3" 2-Bolt gasket on the market. 12 LAYERS!
Tired of the endless searching for a 3" 2 Bolt premium gasket that doesn't blow out? Most aftermarket Subaru exhaust systems need a 3" 2 bolt gasket, however, a quality 3" 2 bolt style gasket is nearly impossible to find. Until now. GrimmSpeed™ OEM Style Gasket, better than OEM quality at an attractive price.
At GrimmSpeed™ we have worked with endless amounts of aftermarket gaskets, none seem to work as well as the multi-layer steel OEM style gaskets. The issue with the most exhaust gaskets is that even if they're multi-layer, they're not completely constructed of Stainless Steel which leads to leaks. Well GrimmSpeed™ has your answer, a premium multi-layer steel w/ stainless steel fire-ring gasket at a great price.
- 100% Thicker than OEM Gaskets
- 304 Stainless Steel Fire-Ring
Applications:
ALL 3" Subaru/EVO aftermarket exhaust systems

Reviews
"I was literally shocked at how fast this got to me. Literally a day and a half after I ordered it. 👍🏾"
High Quality
"while I cannot attest to it's performance just yet, as bought for the down pipe to converter flange pipe on a Mertop racing high flow cat setup for my 1.8t Audi TT, and have not installed it yet. The quality is fantastic, and the Grimspeed service was great as well, I have a second 2 bolt flange on my Malian rear catback system for the same car, should have ordered one for it, so will be doing that before the exhaust is installed for sure"

"LIVE IN THE RUST BELT OF THE UNITED STATES OR EVEN OUTSIDE OF THE USA? YOUR STATE OR PROVINCE LOVE TO POUR SALT ONTO THE ROADS LIKE MCDONALDS POURS SALT ON THEIR FRIES AND THEN YOUR GASKETS KEEP RUSTING OUT?
