exhaust drone - Toyota Yaris Forums

corradovr6 · 10-10-2021, 06:20 PM

Recently joined the forum - really good site and loads of great info!

Bought t-sport 2002 recently and have been working my way through rectifying niggles etc. One such annoyance is the droning from the exhaust from around 2500 to about 3200 rpm. Really very intrusive in the cabin. It looks like the rear heat shield may not be there as the boot carpet and floor area get quite warm too - i've just added a few layers of Damplifier there as the floor is really thin! Just wondering if the two are related?
Anyone else had that drone and if so, what did you do to reduce it?
Thanks

They are high revving tin cans at the end of the day. But as you already said sound deadening mats make a huge difference.

Haha good description! Just changed the backbox which has reduced the drone but at 2500 to about 3000 its quite prominent. My old 1.3 cdx never had this and as they're practically identical (2nz and 1nz) i assumed it would be the same here?
Does adding weights to the exhaust do anything?
