The Cobb turboback was designed to be everything your were looking for in an exhaust system -- a complete, truly engineered system, the least amount of turbo lag, optimal performance, tasteful looks, and unparalleled durability without a loud and obnoxious exhaust note. The end result is the Street Turboback.

Constructed purely from 304 Stainless Steel, this system features Cobb's cast stainless steel bellmouth to mandrel bent 3" piping, a state-of-the-art metallic substrate catalytic converter, a stock-style flex gasket, the 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.

The STREET Version includes the high-flow catalytic converter. The RACE version does not include any catalytic converters.

This system replaces all the stock exhaust from the turbocharger to the tail pipe and is 100% bolt-on using factory hanger locations. Includes everything necessary for installation.
