Years back, I slowly lost a second in the 1/4 mile and gained it back instantly as my catalytic converter gradually plugged up and then I fixed it. No headers before or after. The only item touched or changed was the cat. To attribute the above 1 second improvement to the headers alone, especially when it includes a whole new and improved exhaust system, is flawed thinking.
I am a fan of headers, especially the proper headers for the application, but wild assed claims crediting headers for all the gain coming from a complete exhaust system overhaul, where certain parts (the cats) could have been severely clogged, is nuts.
