Doug Thorley is making headers for the '00-'04 Xterra. This will be an awesome product and the headers will be available in April for the NA engine. Thorley has agreed to test fit the headers on a S/C to verify fitment and thus, allow them to offer the headers for the S/C as well but they need a donor vehicle to test fit the headers on:

Anyone live near Corona with a S/C they would be willing to lend Thorley to test fit headers on?
