    Want to improve the performance of your 2008-2010 Cobalt SS Turbo/HHR SS? A MPx downpipe is a great choice for faster throttle response, higher boost levels and more horsepower.

    This downpipe is made from the following details:

    - Solid 7-9 horsepower increase over stock downpipe.

    - DIRECT replacement, no cutting, welding needed.

    - NO check engine lights!

    - No modification of engine oxygen sensors needed, direct installation!

    - Made completely out of 3 inch T304 Stainless steel for long life, durability and great looks.

    - Made out of 16 gauge thick stainless steel.

    - Hangers are made with 400 series stainless steel for strength.

    Flex pieces are full stainless steel, and are triple lined for great flexibility and durability.

    Note: This product includes the downpipe, mounting hardware, and a 3-bolt gasket. No gasket should be required for the odd-shaped 4-bolt flange on the manifold side of the downpipe, as this flange mates to a cast surface.
