This time, we would like to report on the current status of the development of the sports muffler for CX-5 gasoline vehicles.As some of you may know, the current tuning muffler has noise restrictions during acceleration, so in order to comply with safety standards, take a performance certification test (acceleration / proximity noise regulation) at a public institution. You have to pass.

This time, I took the gasoline 2.5L turbo and NA, 2.0L. Prepare three development cars and take the exam.Of course, all three have cleared the regulation value.
In particular, this muffler has a lot of "boosting" from 2.5L turbo customers.From now on, we are planning to start mass production and release it in February.It's almost over, so please wait for a while.
The image is a muffler for diesel and gasoline vehicles.It can be seen that the silencer of the gasoline car is so big that it does not seem to be the same car.

DPF (Large Exhaust Gas Purifier) ​​reduces the volume of diesel vehicles, so only small silencers and resonators can meet safety standards, but gasoline vehicles do not.
Moreover, the sports muffler is designed with the highest priority on exhaust efficiency.Therefore, in the limited space where mass-produced silencers are placed, two silencers are connected in series and laid out diagonally in order to keep the volume as straight as possible and to ensure durability.
I think the design is a little aggressive and makes you feel "motivated" ... (laughs).
For a gasoline turbo engine, an easy-to-understand equation such as "tuning of intake / exhaust system" = "power-up!"Of course, the development of intake system tuning parts such as ram air intake and intake suction is also in progress at the same time.
We will propose intake and exhaust tuning combined with this sports muffler, so please look forward to it.
