From zardSlip-on Silencer...

Replaces ZARDSlip-on Silencer. (Compare to ZARDExhaust System or Normal muffler?)
I checked the weight on the manufacturer's home page before purchasing, and it was about the same for both ZARD and AKRAPOVIC.

Installation is very easy, just touch the screws on the hanger and the exhaust pad for a total of 3 screws!
The tightening Torque was written in the instruction manual.
The rest was a quick check for exhaust leaks.

I was very excited when I turned on the Engine, but the volume was exactly as expected and not at all different from that of a normal muffler. 。 （The volume per 5500 rpm is almost the same as the Idol volume I measured simply with TaBrett's app when I had the Normal muffler on. I felt that the sound was a little too Large when I was driving. Also, ZARD was not a blast when I removed the Baffle, but it was a very energetic sound.

The sound quality when running was racier than NORMAL (Brush-bo effect?). Compared to the ZARD muffler, the ZARD had a lower sound. However, the sound had a muddy taste, or perhaps it was because there were many parts such as intermediate pipes and covers, and there was some noise mixed in. 。 In comparison, AKRAPOVIC has the sound of Engine blowing up. [Color] Clear and favorable.

The body is larger than I imagined, but the design is sharper than normal and looks more resilient. View detail
