How hard is it to remove the exhaust manifold on a Sunfire 03 Ecotec?
I am thinking about porting my manifold, but I dont want to have to go through hell n' back just to gain 2 hp.
if you drive in areas with road salt it will be a bitch , and youll need air tools , and prob have to replace the bolts or studs that hold the down pipe to the manifold
not worth it, don't bother
yeah not worth it. replace it with a header and you will be better off.
