I'm in the middle of putting these on finally. Going to the dyno Sunday and I'll see for myself.

On a stock LS3 with headers janetty racing picked up 10 more numbers with 2” over 1 7/8”. That seems to be the general consensus. And as always bo will show us his results because he’s an apples to apples kind of guy! Just like with the 416 vs bottom end with the same cam.

Thanx for reminding me. I picked up zero until after peak power. In the overrev it was 8rwhp 2" vs 1 7/8"
Don't know about bottom end changes because my stall absorbs everything pretty much below 5500rpm.

Any pics of them installed? Any fitment issues?

I just recently put BMR mounts on and had to loosen it up and shift the engine over a touch because they are slotted.
