Using your DC Sports Muffler Delete System is easy. First, find a flat and safe surface to park your 2015 - 2020 Subaru WRX/STI. Then, use basic tools to attach the system directly to your existing OEM equipment as it's made to fit without any modification. During installation, make sure all the bolts are tightened properly to avoid any rattling or loosening. When it comes to maintenance, regularly check the pipes and tips for any signs of damage or rust. You can clean the stainless - steel parts with a mild soap and water solution. Avoid using abrasive cleaners that could scratch the surface. If you notice any unusual noises or performance issues, it's a good idea to have a professional mechanic take a look.
