What are these Mufflers and Headers?

Putting an expensive header on that car will make absolutely NO difference in the way it runs whatsoever. Only thing you'll notice is a lightened wallet.
I would fix/replace that crushed tube, and get rid of those cherry bomb mufflers. Replace them with a set of turbo style mufflers, you'll like the sound (and so will the ol lady) and it won't be annoying. I would run the pipes out under the bumper if they aren't already.

My 2 cents.

Thanks George,
Would I have to Weld in a new tube to fix the crushed one? I have 2 good muffler shops right here in town. Do you have a ball park $$ that I should plan to pay them to fix the header.(The Passenger side is fine and sits a couple inches higher than the drivers side. The car is pretty fast but I just cruise it a low speeds and don't care about a few Hp. BUT....If turbo mufflers will add Hp, That's a nice bonus. I definitely want to run it out the back and put on nicer chrome tips.

Thanks for the reply and a little more advice on getting rid of the Flat spots on the header Tube
