GrimmSpeed understands that many Subaru owners replace all exhaust gaskets at once when installing aftermarket parts. That’s why we offer this complete gasket kit featuring our premium multi-layer steel gaskets with 304 stainless steel fire-rings—now at a discounted package price for maximum value.

After testing countless aftermarket gaskets, we found that multi-layer steel OEM-style gaskets consistently outperform the rest. Most gaskets—even OEM—aren’t fully stainless steel, which can lead to leaks. GrimmSpeed’s solution ensures leak-free, long-lasting performance.

Key Features:

• 22% thicker than OEM gaskets for superior sealing
• 304 stainless steel fire-ring for durability and corrosion resistance
• Premium multi-layer steel construction
