Do LG super pro headers have different runner lengths between 1 3/4" and 1 7/8"?
I'm on the LG Motorsports site and I'm trying to make sure I understand the header options right...
I'm looking at the headers for my '09 C6 LS3 and it shows:
1 7/8" long tube headers:
Then it shows:
1 3/4" headers:
So the 1 7/8" size has shorter runners than the 1 3/4" size? I guess I'd never really paid attention and thought they were identical designs, just with different diamete pipes.

Personally,
Unless you are going forced induction the 1 3/4" is going to make more total power across the board and really focus in on torque production, which in the end is what makes the car fast.
Only in a few occasions have we used the larger pipes on an LS3 and it made any kind of difference on increasing power over the 1 3/4 systems.
Blown and bigger cube engines...it is a slightly different story but I even use the 1 3/4" on a lot of the LS7 pacakges as well.

The larger pipes were done to focus on higher end HP, which is also the reason for a shorter pipe. We also had to work within the space limiations of the car between the bellhousing and the frame with the larger pipes, which placed the collector there.
