Hey everyone, im interested in buying a HKS 4 branch manifold that someone is selling but i wanted to know if it will bolt on to the original exhaust? Also will i get much performance gain using the original exhaust with it?... Thanks.

 

Yes, it will bolt on to the stock parts (actually bolts on to the catalytic converter, not the exhaust) with no problem.

As much performance gain as compared to what? It flows more air than the stock manifold does, so an aftermarket exhaust would help, but either way it should be a good improvement over the stock manifold.
