No, you don't need the insulation under your hood. Personal preference is what it boils down to. Nor do you need insulation under your carpeting either. For me, I like it. It's just nice to have, to help deaden the sound and vibration noises coming your motor and road noises, if thats what makes your clock tick. Just as you don't need many things, ie, radio, clock, tachometer, interior lights, doors, they are there for a reason. The question is, do you want and need this? I, myself, don't do any "off roading", mine is a daily driver . I like the ride to be as soft and quiet as possible. I want to be able to carry on a conversation with someone sitting next to me, without needing to yell. I do like hearing the motor (exhaust pipes) though. I would love this insulation under my hood. Just as I have put insulation under what Jeep calls carpeting and along side the kick panels. The road noise has gone down considerably. I am considering insulating the hard top also. Plus, it's much warmer in the wintertime. To each their own. Ain't America great! You gotta love it here.
I'm lookin at your setup and seeing its not really cut out over the mc. It's off to the side of it? I wonder why? I'll have to go look at mine now and try to finger it out.
