I know someone already said it but, for sure these will flow better than stockers? How complicated to make this work with a 3" downpipe and 3" dual exhaust? Any extra unforseen work with that kind of setup from what you guys have already done. I currently have a stock exhaust setup on my car right now (up-pipe, downpipe, crossover, etc.) I want to upgrade soon to 3" Dp and pipes so obviously I need to change at least the stock crossover, and mind as well at that point do the headers as well. As long as it would be an upgrade. Just wanted to see if what you guys have already done, works with what i have in mind. Its obviously next to impossible to find good Kenne bell or Postons stuff. This seems like the way to go. Hats off to those that have worked so hard on making this work and so graciously sharing it within the community for all to benefit from. Any help to answer my concerns is greatly appreciated. You guys rock for doing this! Nice work. They look really good, and will benefit all who are hopelessly pulling their hair out like me to find a good aftermarket header. Thanks in advance. - Jimmy
