bigger mas air will it help?
I have a 408 built fairly decent, I am still running the stock mas air, will a aftermarket one gain me anything noticeable? Any suggestions on brands and size?

27 rwhp, somethings wrong, my friend disconnected his SLP cat back on his 408 and only gained 4 rwhp. He did this because he was trying to determine if he should run cut outs.
My '09 Vette as per GM only gains 6 hp, not rwhp, with the NPP exhaust which is supposed to, at least partially, bypass the muffler.

A bigger MAF will help only if you already have a lid, throttle body and intake to take advantage of it. No use going with a stock replacement lid, to an 100mm MAF, on a 90/90 intake ... or worse an LS6 intake. Think of the intake system like your exhaust, you wouldn't run a 2-1/2" I-Pipe off of your 3" Y-pipe to feed your 3" muffler now would you?

Yes!
If you upgrade to the 85mm MAF with our Fast Toys 85mm lid and get a proper tune, you will easily see a siginificant HP gain. We've had stock cube, cam only cars pick up .7-.8 MPH in the quarter. A heads/cam or larger displacement motor will gain even more.
