A customer wants us to make 90mm diameter muffler for full tuned car with turbine exchanged.

1. A car should keep the clearance from the ground not to touch the silencer.
2. Separated flange should be back side as possible and should be close to the floor.


The clearance between muffler and ground was kept and could make the custom muffler with a beautiful finish. Now we are checking the power with our muffler.

After finishing the measurement of power rate and find the power gained, we will start to manufacture in mass production for the other users. If the power could not be gained, we will re-design and develop for a customer again.

The design and developing fee were bear by our company and we will sell this muffler for all customers.
