The HS02SW1GTP Invidia N1 Cat Back Exhaust is a top - notch choice for your 2002 - 2007 Subaru Impreza WRX and WRX STi. It comes with new gaskets and hardware. Crafted from 304 stainless steel, it's built to last. The 3 - inch piping diameter and 4 - inch stainless exhaust tip enhance performance and look great. The resonated mid - pipe and single - exit design give it a unique sound. It also includes a silencer. The exhaust hangers are welded onto OEM locations for a direct fit. 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 system. Then, install the Invidia N1 exhaust in place. Make sure all the connections are tight and use the provided new gaskets and hardware. Once installed, turn your car on and enjoy the new sound. As for maintenance, regularly check the exhaust hangers to ensure they're still welded securely to the OEM locations. Keep an eye on the gaskets and hardware for any signs of wear. If you notice any rattling or strange noises, it might be a sign that something needs to be tightened or replaced. Also, since it's made of 304 stainless steel, it's quite durable, but you can still clean it with a mild stainless - steel cleaner to keep it looking its best. And remember, if you're using the factory downpipe, you'll need to get a catback adapter from one of the recommended brands.
