The HS15STIDTG Invidia N1 Titanium Cat Back Exhaust is a top - notch upgrade for your 2015 - 2021 Subaru WRX or WRX STi. It comes with new gaskets and hardware for easy installation. Crafted from Grade 5 Titanium, it offers excellent durability. The 3.15 - inch piping diameter and 4 - inch titanium exhaust tip not only look great but also enhance performance. With a non - resonated mid - pipe and dual - exit design, it produces an aggressive sound. It includes a silencer for some noise control. The exhaust hangers are welded onto OEM locations for a direct fit. This catback exhaust is one of the best in terms of sound, fit, and appearance. It's easy to install: just remove the old quiet exhaust, put in the Invidia N1, start your car, and enjoy. If you're using the factory downpipe, you may need a catback adapter from GrimmSpeed, Invidia, or Torque Solution.
Using this Invidia N1 Titanium Cat Back Exhaust is a breeze. First, park your Subaru WRX or WRX STI on a flat surface and make sure the engine is cool. Remove the old exhaust system carefully. Then, take the new Invidia N1 exhaust and align it with the OEM locations where the exhaust hangers are welded. Connect it using the new gaskets and hardware provided. Start your car and check for any leaks. When it comes to maintenance, keep an eye on the exhaust for any signs of damage or loose parts. If you notice any issues, get them fixed right away. Also, since it's made of titanium, avoid using harsh chemicals when cleaning it. Just use a mild soap and water solution to keep it looking good. Remember, if you're using the factory downpipe, you'll need to get a compatible catback adapter.
