Cobb 02-07 WRX/STi Catback Exhaust

COBB is well-known for making performance parts that work with your Subaru's factory systems. This catback exhaust is designed specifically for the 2002-2007 Subaru Impreza WRX and STI models. It replaces the factory muffler and piping from the catalytic converter back, changing the sound and how easily exhaust gases can exit your engine. If you're looking to give your Impreza a more aggressive exhaust note and potentially free up a little power, this is a solid option.

This catback is constructed from 3-inch diameter, 304 stainless steel tubing. That means it's built to last and resist corrosion, even in harsh weather. The system features a straight-through muffler design, which helps reduce backpressure compared to the stock setup. This allows your engine to breathe more freely, which can lead to a noticeable improvement in throttle response and a deeper, sportier exhaust tone. The system is designed to fit directly onto the factory catalytic converter, making installation more straightforward. You'll get a more satisfying sound under acceleration without the drone at cruising speeds that can be annoying on some aftermarket systems.

When installing this catback, you'll want to have a good set of wrenches and sockets handy. The kit includes all the necessary hangers and clamps for a direct bolt-on installation. It's a great way to personalize the sound of your WRX or STI and complement other performance modifications you might have done.
