Our development work for Stage 2 of the Toyota Yaris GR has been completed.
In this vehicle we have installed the HJS EWG downpipe, the Wagner intercooler and our own flap-controlled exhaust system.
Our stainless steel exhaust system offers near-standard and unobtrusive driving with the flap closed.
As soon as the flap opens, the vehicle generates an absolutely brilliant soundscape!
The exhaust system costs €2580 including TÜV, flap control and installation (plus the tailpipes).
You can find more details in our product store!
For videos and sound files you can simply contact us or browse our Instagram account (@siemoneit_exhausts / @siemoneit_racing).
With these hardware changes, we have achieved 340 hp and 452 NM.
