I recently bought an EBay 7875 and wanted to share some dimensions/weight differences with the GT45.
GT45= 34lbs
7875= 21lbs
This 7875 has .96 A/R on the exhaust, much smaller than the GT45 which is 1.10 I believe.

I have the On3 Performance 78/75 and thought the same thing when I unboxed it, seemed so small for its size. I hope it performs well for its (low) cost. I will be anxious to hear what you think of the 78/75 in comparison.

I'm starting on my hot side piping now, have a LA 360 running on FiTech 1200 currently, but recently ditched my NOS and swapped from headers to the large port '92 magnum manifolds turned around (pattering after some of what you, Dizuster, and others have done here). Thanks for all of the info you've posted on your setup Subcom, I hope to have something to contribute soon as well.
 
Going to have next to nothing on lag time with the smallest exhaust housing, that's the same size I have for my twins.
