My exhaust manifold has developed a slight leak from the slip joint on the lower pipe. I have a tuning date set in a week so I'd like to try and sell these before then and get something different, rather than finding someone to weld the slip joints for me. Should be an inexpensive fix if you are handy or know someone who is with a welder. These are similar to the Perrin/Agency Power/Tomei headers ...pretty much all the same with the slip joint design. $375 firm
