The HS15SW4GTP Invidia N1 Cat Back Exhaust is a top - notch upgrade for your 2015 - 2021 Subaru WRX or WRX STi. It comes with new gaskets and hardware, and is built with 304 stainless steel for long - lasting durability. The 3 - inch piping diameter and 4 - inch SS exhaust tip ensure excellent performance. The resonated mid - pipe and single - exit design give your car a unique and powerful sound. It also includes a silencer, and the exhaust hangers are welded onto OEM locations for a direct fit. This exhaust not only looks great but also makes your Subaru sound amazing. If you're using the factory downpipe, you might need a catback adapter from GrimmSpeed, Invidia, or Torque Solution.
Using this Invidia N1 Cat Back Exhaust is a breeze. First, turn off your car and let the engine cool down. Remove the old, quiet exhaust from your 2015 - 2021 Subaru WRX or WRX STi. Then, install the Invidia N1 exhaust by aligning it with the OEM locations where the exhaust hangers are welded. Connect the gaskets and hardware properly. Once installed, start your car to enjoy the new sound. Remember, if you're using the factory downpipe, you'll need to get a catback adapter. For maintenance, regularly check the gaskets and hardware for any signs of wear or looseness. Clean the exhaust tip with a mild stainless - steel cleaner to keep it looking shiny. This exhaust is designed to last, but proper care will ensure it performs at its best for a long time.
