HKS GR YARIS PROJECT DEVELOPMENT VLOG VOL.8 

Can’t wait for the GR Corolla in US 👍🏽

It sounds amazing. I wish the USA could enjoy this model

Installed it few days ago, love it!

Well designed Sound 👏🙏😃

Thank you for your commitment HKS 🙏 I hope to enjoy this muffler in 2022!

How much more power does it give?

燃調とらなきゃですかね？

The super turbo muffler is less dB then this one. But super turbo muffler has 30% more flow, and this one has 20% . So this one is louder and lighter? Super turbo muffler is rated for 500hp but no mention about this one? Super turbo muffler is 20kg?

GRMNヤリス対応品作って下さいよ

Would this be better if paired up with direct pipe and hi flow cat

Look up motive video. Fastest GR in the world

正直言うと、スーパーターボマフラーの音質が他メーカーの製品を含めても出色の出来に思える感性の自分からすると、これはいまいちかなぁ…まぁ結局のところPCのスピーカーを通してでは本当のところはわからないんですけどね。

軽自動車みたい

音イマイチ。
