Hi all

Firstly thanks for all your great info.

I have a 97 80 series auto and it seems to have developed a persistent whistle under acceleration.

I first noticed it when I put my foot down to take off around a left hand corner now it does it all the time at around 2100 rpm to about 3000 rpm under load (when accel.). It does it in all gears but not neutral. It's slightly worse up hills. I can only hear it with te windows down.

I have inspected the exhaust but cannot see any evidence of holes or a leak. Could this be an intake problem or an exhaust problem?

Any help or ideas would be greatly appreiated.

cut off the small can on the exhaust that is behind the rear axle...looks like a small muffler...they tend to cause a whistle.

K&N air filters seem to create some intake whistle too...
I have the whistle too... when I first got my 80 I went to my toyota friend and he did an overall check. At that time he said the muffler was going to need replacing.. a few weeks after I started getting the whistle. So I feel its the muffler. Got to save up for the Borla...!

I love my whistle... it makes me feel cool, like I have a supercharger. But mine is bad enough now to whistle slightly at idle...

Not so much, in fact, it might get louder.

My theory is the drain hole that Toyota thoughfull and brilliantly puts in the muffler causes the whistle at higher mileages. You can have a whistle, or you can have an American no drain hole muffler that falls off after 5 years.

I am whistle free after replacing the muffler due to pretzled pipes.

Mine had that at around 150K.
Go back to the tail pipe and see if it rotates.
I had my local trusty mech reweld it to the resonator.
Whistle gone.

Thanks guys. I think I will put up with it if it's not serious.

If it gets really bad I might consider exhaust work. (Or when I finally get around to buying a turbo or SC - :bounce: - dreaming)
