1/3/4 Headers VS 1/7/8

Just heard from a few people that while the 1/7/8s headers will show more gain, they may actually hurt the performance in the 1/4 mile and make less torque in a stock LS3 application?? is this true?? Basically saying that 1/3/4 headers will do better on a stock LS3 than the 1/7/8s+, idk wut to think so i figured id share wut i heard

Who told you this? 1-7/8th headers will make a significant amount more hp/tq than 1-3/4 at ALL RPMs. You've got a huge 6.2 liter engine. I wouldn't even consider 1-3/4...unless they were free. Either go 1-7/8ths or 2 inch...or even stepped.

Yea, good choice...you would have regretted getting the 1-3/4 headers. Did you order them yet or are they still on back order?

I have to agree with you on the 1 3/4" headers, just too small for these engines. But, help me out here and correct me if I'm wrong. I read here in one of the many header discussions that the 2" headers were too big for the 6.2 with there stock aspiration. Thus causing too much loss in back pressure and thereby dropping torque and HP. It was also stated that the 2" primaries were better suited for inducted engines with greater flow. ??????
