Default Aftermarket Intake Manifold LS3

Probably been covered several times already but can't find it. Is there is a better option for improving intake? 2015 Camaro SS. If so, which one? Holley, FAST, MSD, or porting factory? I was sold on MSD until I heard numbers were a myth. Now back to the starting line. Can anybody share valid/actual experience/results?
Thanks.

Depends on your setup. Tell us about your car and intended use. That will help give you some suggestions.

Well intake manifold would be a natural progression for those mods but it's a lot of money for what may be minimal gains on a stock cube motor. Most will tell you the FAST does not really come alive on a stock cube motor. MSD seems to have had a lot of hype but issues have silenced that some. A lot of folks still holding out how on the Vararam and of course Edelbrock is hyping the cross ram intake as well.

At this point more questions than answers. If you can hold out, wait for those new offerings to be released and prove what they've got. I have a ported FAST but I'm also running a high compression 427 which demands more flow.

Keep your stock intake.

Planning on having it ported. That what you meant?

I wouldn't touch the ports. Instead, look at Rick Crawford or Gwatney Performance. They install radius bars to help with airflow. The cost is around $300 to have it done to your intake, and the gains are good for about 10-15 horsepower.

Why not port?
No experience with radius bars.
Why better than porting?

Porting the LS3 intake has yielded little to no results, much like the LS6 intake.

Ok. So what is a radius bar. How does it help? $300 for 10-15hp on a cam engine. Way outside the bounds of what other stuff is doing for even more money. Great deal if it's real. How does it work?

Google "Rick Crawford intake" and read away.

This one has the supports removed. I would not recommend having that done. They are structural to the intake.
