Using your Remark SPT Axleback Exhaust is easy. First, make sure your vehicle is a 2015 - 2021 Subaru WRX or STI and has an SPT midpipe. Then, you can directly bolt it on to the SPT exhaust system. The gaskets and bolts are included, so you don't have to search for them. When installing, follow the normal installation procedures for exhaust systems. Remember, this product won't fit non - SPT midpipes or Type RA models. For maintenance, regularly check the exhaust for any signs of damage, like cracks or loose parts. Since it's made of stainless steel, it's quite durable, but cleaning it with a mild stainless - steel cleaner every few months will keep it looking great and functioning well. Keep an eye on the exhaust hanger rod construction and make sure it stays in good condition to maintain a proper fit.
