okay im looking to do an exhast system on my hhr. has any one came across a good header that they like or would recommend? also i came across this one (http://www.clearimageautomotive.com/...obalt%20SS.htm) for a cobalt ss. does anyone know if it would work? thanks for the advise.

 

I have (2) HHR's one has the Hahn, one has the Cobalt-Addiction..
Both fit my 2.4...

 

oh yeah i have the 2.2. is there a set header size or kind for either 2.2 or 2.4. i heard mixed oppinions.

 

No. The only difference in header for the ECOtec is by company. There really is no specific pipe size for the 2.2, 2.4 or 2.0sc motors.

 

wheres the best place to get a header for the 2.2? the hahn one that i found for the cobalt says it will not work on the 2.2 or the 2.4

 

wish i could give you some info but i never followed up on the exhaust, but i remember looking at a few on summitracing.com.
I was going to wait till i had my car paid off. I had estimated an $800 header back 3", high flow magnaflow cat, super 44 muffler exhaust system. but check summit depending on what you want i think headers ran 150 to 290.

 

i found this...don't know if it helps any.
