I had a Ducati that I drove long ago with a Carbon body Tel-Minioni I bought it because I like the look of it and that slightly dry sound
At the time, there was no such a nice Parenthesis ShotgunType, and even more so, the domestic There was no LineUp setting in Middle class When I saw it, I snapped it off
But this is not for public roads
It's even politely stamped RACE USE ONLY
In fact, if you put this Silencer together for a test drive, you'll find that it's a bit of a high RPM characteristic for city driving It is not suitable Also, the sound is obviously Large
So how can we make it for public roads?
The answer is simple All you have to do is turn down the volume
Now, we will perform the volume control treatment step by step
But this time there is "Binding will be set up Since we want to enjoy the track day, we will make it possible for the car to be put back together within 5 minutes at the site In other words, no welding will be used, only Bolt On
I'm going to put the included Bolt On Baffle on first
→ It's a little lower, but when I measured the volume as required by the Highway Code, it's still as expected It does not enter into the specified value
Next, let's put together the Inner silencer of Universal which is available on the market
This time, I happened to have a 52.5mm OD for Glass made by DAYTONA that I had at home WoolMaterial:I used a Stainless Steel grinder to lightly grind the circumference to make it just right It was fixed to the inner wall of the sunlencer with the screw for fixing
→ The volume has been reduced considerably, but it needs to be lowered by a few more decibelsLarge It is not
Now, let's change from a straight structure to a bulkhead structure in a simple way
It is used to fix the bearing inside the entrance side of the inner sunlenser that has been installed The shaft collar with Screw hole is fixed with a screw at the punching hole of the tube It is a simple sub-optimal way to exhaust through the punching hole in the inner sunlenser tube on the outlet side Bulkhead construction
→ Volume Clear. tone is also dry compared to the OEM, with a BALI ton of voice It has an Italian feel to it
As for the ride, the bulkheaded design gives us more exhaust pressure and brings back the low rpm range, and DASH is oh! It's like
I felt a little bit of fluctuation in high speed driving, so I'm going to enjoy it a little more and make some adjustments to get the right volume and driving feel We are going to take Balance
Special Tools (I used Grinder for a bit because I used Parts from home.) You don't need to use any special Parts or special parts, just use commercial Parts at home and Bolt On for public roads This is an example of how it can be done
I forgot to post the aforementioned processing and noise measurement values when I installed it. 72.4dB at Idling (A) and quieter than the OEMSilencer at 87.7dB at 7,500rpm (A) and it was the same etc.Level as OEMSilencer.View Detail
