Using this BLOX Racing axle back exhaust is straightforward. First, make sure your vehicle is a 2015 - 2021 Subaru WRX or 2015 - 2021 Subaru STi (non SPT) as it's designed specifically for these models. You'll find all the necessary hardware and gaskets in the kit for a direct bolt - on installation. Just bolt it to the 2 - hole exhaust flange on your car. Remember, it won't work with aftermarket exhaust systems or SPT exhaust, so don't try to install it on those. For maintenance, since it's made of T304 stainless steel, it's quite durable. But it's a good idea to regularly check the bolts and gaskets to ensure they're tight and in good condition. If you notice any signs of rust or damage, clean the affected area and consider applying a protective coating to keep it looking and performing great.
