Quote: The Doug's D453 headers are also 8 lbs lighter than the TTi headers. That might not matter to most people, but 8 lbs off the front of a track day car is a plus.
I question why they're lighter, if the basic tube layout is the same, gotta be thinner tubes and flanges, not exactly a plus in my book. Weight in weight, but some places I can stand a few extra pounds for longevity and durability.
