The exhaust gaskets in your new FA24 are in good shape now, but they won't stay that way for long, especially as you modify the car with exhaust upgrades. At GrimmSpeed, they've gotten ahead of the game by introducing FA24 Exhaust Manifold to Turbo, Turbo to J-Pipe and their Exhaust Gasket Set for the 22+ WRX, 20+ OBXT and 19+ Ascent.
GrimmSpeed Gaskets are famous in the Subaru World for good reason. They've worked with endless amounts of OEM and other aftermarket gaskets and found the perfect formula for a durable, cost-effective, multi-layer steel gasket. They use the best available material and add extra layers to our gaskets to allow for more compression on the stainless steel fire ring for better sealing against flanges that may not be machined perfectly flat or have warped over time from thousands of heat cycles. That means when properly installed, GrimmSpeed Gaskets do not blow out like others are known to.
