You should hear the Corolla revved to 4000, trying to jumpstart a van! Ouch!

Earplugs would probably be cheaper and simpler!

I have never driven a small Japanese 4 banger that wasn't loud. Rav4, Corolla, Sentra, Accord, etc. They sacrifice sound proofing to save cost and weight.

Turn up the radio.

I remember my 420sel idling next to my brothers 1991 honda accord. The accord was way louder

My civic is a loud little thing. Most of the noise in mine radiates from the floor and roof. I agree with fatmat throughout the interior. Labor intensive though.

I've already stripped the interior once (for a through cleaning), so I now what that involves

. I'll let you guys know what we go with...

Back in 1975, I had a 1971 Datsun 1200.... Noisy little 40mpg tin box.

I helped a friend line the entire interior, (doors, ceiling, floor, dash); of his even noisier 1967 MGB-GT with shag carpeting.....it was so 1970's Awesome!

And so quiet.
So I proceeded to line my Green kamback Datsun 1200 with 2" of soft cushy foam, AND shag carpeting...ceiling, doors, hatch, floors, dash.... Man, it was double Far-Out!

It was a soft, cushy, quiet, 40mpg machine. (It was cool until the shag carpeting on the ceiling was falling down on my head while driving through Sequoia National Park...not Far-Out man!) So I took a few stitches and sewed it to the headliner.

So I suggest; 2" of soft cushy foam and shag carpeting; I guarantee comments from everyone; but you won't hear them from your mini sin bin; the rolling cone of silence...................... I approve this message.

I've noticed a small decrease in noise when I wrapped my exhaust manifold in fiberglass.

Another option would be to swap covers from a Lexus, if they fit. I know the 90's camry guys like to grab lexus engine covers form the junkyard.

If it's wind noise, adding "vortex generators" aka bumps to the sides of the mirrors can help. They're on most new cars for wind reduction.

A road less traveled would be to try your hand at intake resonators. Glue a dead-end tube to the air intake hose between the filter and throttle body. this modification will take lots of experimenting though

Hmmm... the Lexus hood insulation sounds like a good idea. I'll do some research on that. What are intake resonators? I've never heard of them before.

Now that is a funny story. I can relate to the shag carpet era. it was soooo DISCO, and the in color was Lyme green, or orange yellow.

Heh, heh...orange yellow shag in a kelly-green car........ Far out man!
Actually pre-disco, pre 'Spirit of 76', otherwise it could have been red white and blue mix shag.
