Haven't been on the forums lately- sorry for the delay, been busy.
I still haven't removed the silencers. No real seat of the pants increase, but you can hear the intake now. It hasen't helped w fuel mileage either. Silencer removal will add the real aggressive sound and a few horses.
Why did I do it???
Because I cannot leave well enough alone. Look at my sig.
For those of you wanting to fabricate one, you'll have to do some cutting and buy some tubing, and even trim that. It's easy, just tedious. Since the MAF is attached to the airbox, that's what you'll need to cut off. Don't do this if you do not know what you are doing.
Short Ram and Cold air intakes do add peak HP.
My next project is the exhaust, whenever I get around to finishing up the intake.
Peace.
