The HS02SW1GTT Invidia N1 cat-back exhaust is a great choice for your 2002 - 2007 Subaru Impreza WRX or WRX STi. It comes with new gaskets and hardware. Made of 304 stainless steel, it features a 3-inch piping diameter and a 4-inch titanium exhaust tip. The resonated mid-pipe and single-exit design offer a great sound. It also includes a silencer. The exhaust hangers are welded onto OEM locations for a direct fit. This is one of the best-sounding, fitting, and looking cat-backs. Installation is easy - just remove the old quiet exhaust and install this one. If you're using the factory downpipe, you may 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. Then, remove the old exhaust carefully. After that, install the new Invidia N1 exhaust by aligning it with the OEM locations where the exhaust hangers are welded. Connect all the parts and make sure they're properly tightened. When starting your car, you'll notice an immediate difference in the sound. As for maintenance, regularly check the gaskets and hardware for any signs of wear or looseness. You can clean the 304 stainless steel body with a mild automotive cleaner to keep it looking great. Also, if you live in an area with harsh weather, it's a good idea to check the exhaust for any rust or corrosion. And don't forget, if you're using the factory downpipe, make sure to get the right catback adapter.
