If so, consider that the parasitic HP loss from crank to rear wheels is estimated at approx 20% for an auto (give or take a few %). So if you calculate up from 350 at the wheels, it comes to 420 at the crank. That is some outrageous HP increase with just those two bolt on mods.
Congrats to the OP for Dynoing great numbers with min mods but let's not get carried away here.

These numbers seem suspiciously high.That dyno may need some calibrating.Also some operators are notorious for inflating numbers(it brings em more business from the dyno number braggers) I race several local club members with over 400 hp on dyno sheets that I beat at the track by over a second and I doubt if I make 330 hp.

Sorry but that's not possible not with those 2 mods. The intake won't give you crap and the catback maybe a few, plus you are a a4. That dyno DEFINATELY needs to be calibrated or setup coreectly. Sorry but that's just reality.

ok, 308 vararam intake with power duct and descreened maf 10-15 =318-323, catless slp loudmouth exhaust with x pipe another 10-15= 328-333 or 338. pretty close to 331 if you ask me.

Put a toilet paper roll in your mouth and sit still. Then use a straw. Which one can you breathe through better? Whether you are running down your hallway forcing air down the roll or sitting still, the less restrictive flow is always going to be better. Please send a video if you try this also.
For reference, I have a 2002 M6... Breathless Intake and Corsa Exhaust. I got 329HP/339TQ in 100 degree weather and high humidity.
Also being Catless makes a huge difference, I'm sure there are some other "MODS" not listed... It's clearly not JUST and intake and muffler.

That's ridiculous, less restrictiveness still has an effect separate from "ram" air.

0 is about pretty close 
If you look at the design of the vararam compared to say a blackwing, the vararam actaully has to "draw/pull" air through a couple of tubes for about 2 ft when sitting still (Is that the straw you mentioned?) Better than stock...Maybe, 5-10rwhp on a dyno, not a chance. As far as the dyno, the blackwing would definitly make more hp (hood up)
I installed a FAST90/pro ported LS2 TB, 3" x-pipe, and vararam (from blackwing) on a H/C car and picked up around 14-16 rwhp on the same dyno with same tuner.
How much of that are you going to give to the vararam?? (PS: the 10yr tuner said I would have picked up more ON THE DYNO if I had kept the blackwing, but the vararam would be far better on the street
The fact is, although restrictive, the air filter just isn't that big a bottle neck on a stock engine until you start flowing some major air through it

Unless a person is racing the cost of all that doesn't seem worth it to me. back in the day we didn't have a choice when dealing with 200 HP
I was thinking about headers but now I'm not so sure.
