I purchased the Belanger header/exhaust system for my 2008. I strongly agree with those that have recommended you contacting or e-mailing Lou Belanger directly. Lou is not only extremely knowledgeable but is very accessible. Let me put it this way: I e-mailed Lou about how to retorque the header bolts (instructions require retorquing at 1,000 miles) myself and he called me personally within 1-2 days to walk me through the process.

Given that so few Belanger kits have any issues, my sense is that Lou would not only be willing to assist you as a purchaser of his system but would also be very curious about what is the cause of the problem.
