GrimmSpeed 3" Catted Downpipe w/Black Ceramic Coating (08-14 WRX/08+ STi) 007092

A downpipe is one of the first modifications that should be done on your car, as the OEM downpipe contains two very restrictive catalytic converters. Replacing these with our single high-flow unit will dramatically improve performance potential while maintaining the use of a catalytic converter. Within our complete lineup of downpipes, you have the option to add a high-flow, 300 cell catalytic converter, fully machined and contoured flanges with beautiful brushed tubes and black ceramic coating. Whether you're racing time attack or to work and back, we've got the perfect downpipe for you.

Features:

• Proudly made in the USA - Design, Materials and Fabrication

• FARO Arm Designed - We are at the leading edge of new product design hardware

• O2 Bungs for factory sensor and aftermarket wideband AFR

• Divorced Wastegate for Optimal flow

• High-flow, 300 cell, metallic substrate catalytic converter

• GrimmSpeed Gaskets Included - A $40 Value!

Note: Once you have added our downpipe to your vehicle, you must be tuned. Replacing your factory catalytic converter sometimes causes a ‘cat converter efficiency’ check engine light. You can either use tuning to delete this CEL or you can use a mechanical fix. GrimmSpeed aftermarket downpipes modify OEM emissions control devices and are intended only for off-road racing applications.

Fitment: Fits 2008-2014 WRX, 2008+ STi, 2005-2009 Legacy GT (non-VF46, Manual Trans Only), & 2009-2013 Forester XT
