I have a new, unused Pacesetter header for the Cobalt SS (part number 70-1273)...it has 1.75" primaries and 3" collector.
It doesn't come with a gasket and it doesn't come with the flange connector or bolts. It is the header only. I bought it as a combo with the Exhaust Depot catless DP with the intentions of using it on my Cobalt LS (planned to supercharge my car)...I have now decided I want to just run NA with minor bolt-ons so I'm keeping the DP and selling the header...I want to pick up the other Pacesetter header with 1.5" primaries and a 3" collector.
I am asking $125 shipped which is a pretty good deal in my opinion. This can be used on both 2.2/2.4 and 2.0 SC applications, but if you use it on a 2.2/2.4, you will most likely experience a torque loss in low RPM's.
Any questions, let me know.
This is in Coon Rapids, MN and if you're local, I will sell for $100.
These go for $160-$180 brand new with everything they normally come with. Some places do charge shipping, some don't...but about $175 is a good average price new.
I figure the $50 you're saving can buy a new gasket ($19 from Pacesetter or aftermarket are less than $30). You will also need to have your DP custom fitted to this header or buy the Exhaust Depot catless DP which fits perfectly to this with no modification (but it's $215).
