The COBB Tuning Stainless Steel 3” Turbo Back Exhaust was designed to be everything we were looking for in an exhaust system -- a complete, truly engineered system, that offers optimal performance, tasteful looks, and unparalleled durability without a loud and obnoxious exhaust note.
Constructed purely from 304 Stainless Steel, this system features our cast stainless steel bellmouth to mandrel bent 3" piping, a state-of-the-art metallic substrate catalytic converter, a stock-style flex gasket, our low restriction straight-through muffler that tucks up nicely under the car and ends in a tasteful but not overstated 3.5" double wall tip featuring an etched COBB logo.
**Please note: The catted version is recommended for the 2007 STi, due to possible boost spiking while running catless**
