so I just bought an 09 cobalt ss with the LAP engine... I am about to put my old ss/sc supercharge kit on it.... I wanted to know if the supercharged shorty header with bolt up to the stock downpipe.... I am think I am gonna get the bad-mab header.... I know that only the manuals and the automatics differ at the downpipe...

 

Yes it should it

 

There is no such thing as an ss with the LAP engine. So either someone has put ss badges on an 09 cobalt or it's an 08 or older with the LE5

 

Well maybe someone badged it... but it is the LAP... I'm sure... It has the SAI and the downpipe with 2 o2 sensors... no 02 sensor in the manifold
