Does a 500hp strip only car need open headers or exhaust

What size headers are you running (primaries) ?

On something that is making around 500 or more, I would put on a 3 inch muffler. What type of muffler is really up to you. Its really an opinion, its all in what taste you have.

Example:

A Flowmaster will tend to make the car seem meaner then it really is. A lot of people want that. It is also a very poplar muffler because they sound good.

Another good muffler is the Dynomax race mufflers (bullets or ultra flows)

I personnaly like the Spin Tech Mufflers. They have a unique sound but still tough. I also picked one there quitest one the sportmans xl.
Dont get me wrong, with these mufflers I have mention your car will not be quiet. It will not be as loud as open headers but still loud.
This is a very short list of what is out there, and I am sure there will be more added to the list as the day goes on by other people. You can also download sound clips from the manufacture.
Good Luck
