2008-2014 Subaru WRX/STI Hatchback 3" Stainless Steel Cat-Back System by X-Force

XForce offers a range of uniquely engineered and designed stainless steel bolt-on exhaust systems. These exhaust systems bolt directly to existing mounting points making installation easy.

They are built to perform well, with materials designed for longevity, and like all XForce exhaust systems they & look great! The unique header design increases power throughout the rev range while providing a great engine audio note – make it roar!

VAREX mufflers utilizes patented technology to combine both the design technology of the stock muffler and the performance muffler into one single compact unit. A sophisticated butterfly valve mechanism is implemented to redirect the exhaust gas flow and vary between the two. For higher sound levels, the exhaust flows are directed through the opening path and produce maximum power with a robust sound level (or the “sports car note”) and near-zero resistance.

Fantastic OEM+ Tone

Had this exhaust on for about a month now and I can say it's spot on the kind of sound I wanted for my WRX. The tone is nice and deep at low RPM's and gets slightly louder with more throttle. OEM+ is a perfect description of this exhaust, just enough extra sound and tone without being annoying at all or pissing off your neighbors. I decided to go with XForce after seeing the quality for the money of their headers and catback my buddy purchased for his Mustang GT and I have not been disappointed. The stainless piping seems to be of good quality and the welds are good as well, don't expect them to be top-dollar TIG welds at this price point but this product is an extremely good value for the price that it's at. Oh and it fits on an 08-10 narrowbody hatch if you trim out the bumper on the driver's side :)

OEM+ and nothing more

OEM+ is a perfect description. Very slight sound improvement over stock, I hardly notice the difference honestly. Nice quality parts and good fitment. If you’re looking for an exhaust that’s noticeably louder than stock, choose a different one. But for what it is, this one is nice

Awesome OEM+ Exhaust

I've been running this exhaust for a few weeks and I am very happy with the x-force! Install was pretty easy, but getting the pipes to slide together and align correctly was challenging.

John Jaekels
Perfect OEM+ sound

This exhaust is literally perfect. It has an OEM+ vibe, sounds great but won’t wake up the neighborhood. Very low drone. Overall very pleased.

Andres Hernandez
Great exhaust

Perfect exhaust if you're looking for an upgrade from stock. Without being to loud.
Fast shipping as well.
