This GrimmSpeed exhaust gasket is a perfect fit for your Subaru. It's designed to work with 2002 - 2024 Subaru WRX and 2004 - 2021 Subaru STI models. Note that it only fits 3 - inch Subaru aftermarket exhaust systems, so please check compatibility before buying. The gasket features a durable multi - layer stainless steel construction with 7 layers, and it's 22% thicker than the OEM gasket. This extra thickness ensures an optimal seal. Most aftermarket exhaust gaskets have issues, like not being fully made of stainless steel which can lead to leaks. But GrimmSpeed's gasket has a 304 stainless steel fire - ring, offering a premium solution at a great price. It's sold individually, so you can get exactly what you need.
Using this GrimmSpeed exhaust gasket is easy. First, make sure your Subaru's exhaust system is the right fit (2002 - 2024 WRX or 2004 - 2021 STI and 3 - inch aftermarket). Before installing, double - check that the gasket is in good condition. Simply place the gasket between the downpipe and the 3 - inch catback exhaust as per your vehicle's setup. When tightening the bolts, do it evenly to avoid any uneven pressure that could cause leaks. As for maintenance, periodically check the gasket for signs of wear, like cracking or rust. If you notice any issues, it's best to replace it right away. Remember, this gasket is for 3 - inch aftermarket exhausts only, so always verify compatibility before making a purchase.
