HS02SW1TRG. Fitment: 2002 - 2007 Subaru Impreza WRX and WRX STi. Features: Comes with new gaskets and hardware. Made of Grade 5 Titanium. 3.15 - inch piping diameter and 4.00 - inch titanium exhaust tip. Non - resonated mid pipe with a single - exit design. Includes a silencer. Exhaust hangers are welded at OEM locations for a direct fit. The Invidia N1 offers an amazing sound and look for your GD WRX/STi. It's super easy to install - just remove the old quiet exhaust and put this one in. If you're using the factory downpipe, you'll need a catback adapter from GrimmSpeed, Invidia, or Torque Solution.
Using this Invidia cat - back exhaust is a breeze. First, turn off your car and let the engine cool down. Then, remove the old exhaust carefully. Make sure to keep track of all the bolts and gaskets. Next, install the Invidia exhaust. The exhaust hangers are welded at the OEM locations, so it should fit right in. Connect all the parts and tighten the bolts. Now you're ready to turn on your car and enjoy the great sound. As for maintenance, regularly check the bolts for tightness. If you notice any rattling, it might mean a bolt is loose. Clean the exhaust tip with a mild metal cleaner to keep it looking shiny. Remember, this exhaust is quite loud, so be considerate of your neighbors when using it.
