HS15SW4TRG. This exhaust is designed specifically for 2015 - 2021 Subaru WRX and WRX STi models. It comes with new gaskets and hardware, and is constructed from Grade 5 Titanium. With a 3.15 - inch piping diameter and a 4 - inch titanium exhaust tip, it features a non - resonated mid pipe and a single - exit design. It also includes a silencer, and the exhaust hangers are welded onto the OEM locations for a direct fit. The Invidia N1 is a great choice for your VA WRX/STi. It has an amazing sound, perfect fit, and great look, especially with its full titanium construction. Installation is a breeze: just remove the old quiet exhaust, install the Invidia N1, start the car. If you're using the factory downpipe, you'll need a catback adapter from GrimmSpeed, Invidia, or Torque Solution.
Using this Invidia exhaust is super easy. First, you need to remove the old, quiet exhaust from your 2015 - 2021 Subaru WRX or WRX STi. Then, take the new Invidia exhaust and install it. Make sure to use the new gaskets and hardware that come with it. The exhaust hangers are already welded onto the OEM locations, so it should fit right in. Once it's installed, you can start your car and enjoy the great sound. One important thing to note is that if you're using the factory downpipe, you'll need a catback adapter. You can get one from GrimmSpeed, Invidia, or Torque Solution. For maintenance, keep an eye on the exhaust tip and the piping. If you notice any signs of rust or damage, clean the affected area with a mild cleaner. Also, check the gaskets and hardware regularly to make sure they're tight and in good condition. This will help keep your exhaust working well for a long time.
