I've already read the pages & pages & pages of exhaust opinions, header opinions etc. But nowhere did I find anything that addressed what I'm looking for.

Best header choice to improve torque (i already have a 3" cat-back). Not a high winding, high horsepower (yet), wind it up to 6000rpm engine. But a primarily 3000rpm & under "daily driver" that stays under 2300rpm (i checked it out today) under normal driving conditions.

Think of it as.....For a Rockcrawler.....Main goal is to produce torque with little regard to horsepower. Which is also why I have retained the TPI & stock runners, not gone LT1 or siamesed runners.

1 1/2"? 1 5/8"? 1 3/4"? primaries?

350TPI, possibly going 383 in the future & still TPI. And no, I'm not just going to throw in 4.10 hears. I have 3.27s now & possibly going 2.73s later (10-bolt swap), which is another reason to build torque for this daily driver.

 

Nobody has any thought or ideas on what would be best suited for torque improvement?

 

DYNO DON headers with dual cat gets my vote

 

1 1/2 inch or the smallest primary size is better for low end torque.
