I have XS racing headers for v6 05 altima. sounds fricken sweet and is stainless steal with blueish tinge to area around manifold. It is also cat delete and you will need 02 sims or a tune for no cats. Pics will be comming soon. What you get, front and rear headers, down pipe and straight pipe to factory piping, orginal cost was 350 letting it go for 150 and it has no damage!!! email roadrash928@aol.com.
