all engines have exhaust headers but the headers your thinking of are aftermarket performance headers, the ones on the 440 from the factory are made of cast iron.
My opinion, No.
no such thing as an exhaust fuse.
One exhaust system.
New headers, exhaust, performance chip, tidal wave supercharger. All these can help boost your performance in your Charger. It has been said when you add the tidal wave supercharger that you will be able to keep up with an Srt8 model. All these upgrades are also legal and will pass inspection.
I added: Hypertech chip, K&N air filter, headers with dual exhaust. The best improvement came from the headers.
on both sides of the engine block.
about 5 - 10 hp
it will help preformance more than millage
Back of the block, to the left of the exhaust pipe.
