GR Yaris Resonator delete on stock exhaust system

[Onehp]

Quick drive report.
I'm driving with fake sound off and all stock, the three pot character was coming from the engine bay. Now it has moved back and the car feels more 'whole'. When driving sedately can't notice any difference really, but giving it some the car is more fun for me.

So here is some more sound footage. When not listening directly behind, the difference is more subtle. My subjective impression remains as above, all in all, it is still discrete and still very much in 'factory' levels of volume. Except cold start, then it is definitely noticeable.

Sounds pretty good. Glad it came out well for you.

And thanks for the footages.

@GRunt is this mod possible to get approved by TüV?

Normally not because there is no ABE or EG number for this part. in Germany it's called Vorschalldäpfer. Removing this part is resulting in not getting a TüV approval and loosing insurance as well. If you get into a police control that knows what they are doing, the car will be decommissioned.

Some people put fake resonators on the car. This is illegal as well but not so easy to recognise.

It's possible to do a Einzelabnahme of this part or the entire car. A friend Was building a motorcycle from scratch. Own wielded frame, heavily modified BMW engine, own designed Exhaust and intake system and so on. He had to approve every single part as single case and the Bike as a whole at the end. This was pretty expensive and he had to fulfil all noise and emissions standards as well.

So it's theoretical possible, but very expensive and needs a lot of effort. Just not worth it.

Not worth it. Wonder how the new HJS exhaust sounds...

My loud cold start was partly because the exhaust wasn't properly aligned giving tention on the rubbers transmitting sound, went up ramps this morning and aligned it all, advantage with clamps there is some wiggle room and length adjustment (vs welding a pipe). Now cold start is quieter - still loud but ok.

Also noticed that at tickover, sitting behind the wheel and the exhaust hot, I can actually hear a distant but deep 3-pot rumble from the rear - still discrete but with the character that was missed before.
