HS02SW1GTR. This Invidia N1 cat - back exhaust is designed for 2002 - 2007 Subaru Impreza WRX and WRX STi. It comes with new gaskets and hardware, and is built with 304 stainless steel for durability. The 3 - inch piping diameter and 4 - inch stainless exhaust tip ensure excellent performance. The resonated mid - pipe and single - exit design give a unique look and sound. It also includes a silencer. The exhaust hangers are welded onto OEM locations for a direct fit.

Using this Invidia N1 exhaust is a breeze. First, turn off your car and let it cool down. Remove the old, quiet exhaust from your 2002 - 2007 Subaru WRX or STI. Then, install the Invidia N1 exhaust by aligning it with the OEM locations where the exhaust hangers are welded. Make sure all the gaskets and hardware are properly in place. After installation, turn on your car to enjoy the new sound. Note that if you're using the factory downpipe, you'll need to get a cat - back adapter. For maintenance, regularly check the exhaust for any signs of damage or loose parts. You can clean it with a mild stainless - steel cleaner to keep it looking good. If you notice any abnormal noises or performance issues, have it inspected by a professional.
