We'd have to see the sheet on it. Ted did a test with ARH headers and the 2in primary's gave the most gains and didn't lose lowend Tq over the 1 3/4 or 1 7/8. I'd be more concerned with fitment. There's not a lot of space down there and from the pics i've seen, the 2in primary's are cutting it close.
