    When you get the cam installed they'll tune the car for that intake, obviously, but yeah, depending on how aggressive your cam is you'll definitely be leaving power behind. You should be able to find a used varraram or rotofab on the site. I know I'm going to be selling both of mine here in a couple days.

    I wouldn't worry about it. Just get a good filter for the stock one until you can get what you want.
    Also cheap headers are a waste of money if you ask me. I have the jba long tubes because they were on sale and they were as cheap as I wanted to go. Also I had the ability to clean them up. I took a die grinder to all the welds on the inside and collector. They are 409 ss and I painted and wrapped them but still have little rust. I wish I would have gotten better even tho I plan to turbo in the future and they were only temporary.
    Just my opinion tho.
    Good luck.
    I bought cheap headers but they are 304SS not 409SS. I did not want to pay 3 times the price for maybe 8 to 9 HP.
