A company called JTR has come out with a header... but I believe its only 49 state legal. The cat in the stock manifold has been removed in the header and requires some modification to the exhuast system for it 2 work. If you have a scanner that would also be a good thing, because the computer has to "learn" the new header into the system according to the website. Retail on it was $599.99 I think.
