Cobb Catted Bellmouth Downpipe 3" WRX 08-14 / STI 08-17

Regular price $595.00

The Cobb catted bellmouth down pipe for the Subaru WRX 2008-2014 / STI 2008-2017 is CAD designed and 3 inches in diameter with a high flow catalytic converter to increase efficiency of flow rate of the restrictive factory unit. Cobb constructed this down pipe with 304 stainless steel for corrosion resistance and longevity in mind. 

The end piping of the down pipe tapers to a flange that uses the stock gasket and factory spring bolts to aid in flex and proper fitment. This provides compatibility with any cat-back exhaust that mates to the factory cat section.

Features:

  • CAD designed cast turbo outlet 
  • 304 Stainless Steel 
  • Custom spun metal substrate high flow cat
  • Two O2 bungs for factory & aftermarket sensors
