Engine too loud

Hi guys

I want to use my patrol as a daily driver. However its noisy in the cabin and I find it annoying. I thought it was air leak at high speed and have changed door & window beading and silencer as well.

While the noise as reduced, its far from being quiet. I plan to get Hushmat or Dynamat from US for the hood as well as floor.

What else do you guys suggest to make it more quiet in the cabin?

At highway speeds, our van was so noisy we had to raise our voices to talk. I used a heavy pitch based underbody coating and whacked some thick second hand woolen blankets under the carpet. Way better now.

I would suggest cranking up some banging tunes mate, gets rid of all unwanted noise ;)

Is it exhaust or the engine noise you're concerned with

Strip everything out of the front of cabin and apply some sound absorbing mats {like pink batts}
even great to stuff into the 1/4 panel cavity, you'll be amazed how much noise you lose

It's probably your tyres that are making heaps of road noise maybe get a hold of road based tyres like at-s as spares and change them over when you 4wd

Well underbody coating never occurred to me. Will have to source that. I know 3M has one with a rubberised base. Qatar's got a lousy aftermarket.

I thought it was the silencers and had them replaced. But it is the engine itself. And may be the A/C fan too. I plan on getting a Pertonix Ignitor. Would that help?

Can you describe what the noise is, or maybe record it on your phone and post it up on here?

It just a loud noise. Like the ones big trailers would make. And most of it finds it way inside. I recently found a lot of noise entering thru the hole for the gear levers (both of them). Dont know what to do with those. as I dont know what parts went into it originally. I will upload a pic of it.

cant seem to upload the picture. Some one told me the radiator fan is directly coupled with the engine. i.e as the rpm increases so does the fan speed and the noise with it. Is that right? Is there any point in de coupling it?
