For the TurboCharged version of the 2008 2009 2010 Cobalt SS only. Will NOT fit the Supercharged or Naturally Aspirated versions of the Cobalt SS!

Designing a down-pipe is usually a simple feat right, no. It's pretty easy to make a make a pipe look like a factory piece. The difficult part is making a pipe with a cat inside to make very close to cat-less power. Our down-pipe was able to extract the optimal amount of flow out of the down-pipe with a cat in place. This was done with strategic placement of metal matrix catalytic converter and 3 inch T304 Stainless piping. By playing with the cell count of the cat and the placement we were able to achieve a part that does not trigger a CELand supports high power levels.

For those who are not concerned with running a cat's at all. We do offer a completely catless version which doesn't trigger a CEL either. We have the option for your power needs!

Cat-less version for Off-Road and Racing use only, NEVER to be used on the street or highway. Great for track days or the drag strip. NOT emissions legal.
