Sorry i think i'm being dumb on this one 
These are long tubes, connecting to the y-pipe, obviously they're a combo manifold and test pipe.
On a DE engine, like '03 and '04, they're making gains throughout the range? Obviously over catted, but is this still gaining over the ART pipes?

not doubting it most short tubes arnt actually designed properly and instead are simply designed to fit compact areas. then compared to stock............well anything is better haha.
jerry, agreed... but we do have data that indicates how these headers will perform on our motors. the consensus of the several different dyno sheets is that you are going to gain power everywhere, particularly over the best shorty headers and cat-delete pipes out there, over the vast majority of the powerband and break even with them anywhere you are not gaining. these headers undoubtedly are a win and the extensive testing done by that user proves it. ive had longtubes on literally a dozen cars and havent gone wrong yet.
