While these look cool, I've been told by a credible source that they don't match up performance-wise to the blackwing or stinger because of the restrictiveness of the bends (even the 45deg ones, but especially the 90deg ones)... I was gonna go that route when I had to give up the Vararam for the TS front end, but got talked out of it by a vendor (who could have just let me spend the extra money on the twin filter system, but chose instead to be honest and communicate his shop's real-world experience with performance results). Thanks NATE at CorvetteGarage!!!
I wonder if the MAF that he was using still had its screen in it. The screen converts turbulent flow to laminar flow - slows and straightens the air flow past the wire element in the MAF. One thing I don't like about some intakes is their metallic runners. Heat from the engine bay may get radiated into the tubes to heat up incoming air.
This is why if I did have a Twin-Flo intake, I'd be sure to open up the fog light panels and install Z06 screens. The resulting outside air would be directed at the cones - a good thing in my book.

I had the RM Racing Twin Flow - which looks like this, except it is a GM licensed product. I never had any issues with it either - though I've heard that issue about turbulence too.
I switched over to a Blackwing about a year ago when I a buddy offered one for free that he wasn't using. I didn't notice a big difference between them, though I do hear more intake sounds.
Never had the car dyno'd with either one, so I can't say if I got more hp or less from either.
Had a RM on my 98 Vert 6spd. I could notice the difference. I installed it 2 months after my cat back system. Cat back did not seen to do much but the air intake did. Of course it could have been more to do with both sytems working together.
I also took a 7/8" hole saw and put a series of holes in the panel next to the fog lights. Never did put in screens as the holes where neatly done. Cost = nothing
