I was not dissatisfied with the sound and performance of the OEM Exhaust System, but when a new product for MD47 was available at a reasonable price, I purchased it. (Compliments.) When opened, the engine blows smoothly. However, as it is inspection standard compliant, the sound pressure is there for better or worse, and the intake sound is more Large when it is open, which is not much different from the OEM. What I like about it is that it is about half the weight of the OEM, there is no afterfire that bothers me when I open and close it fully, and the machining accuracy is good and the installation was easy. All in all, I think it is Exactly for a change.
Very light compared to OEM (by 3 kg), looks very good, throttle response has improved significantly especially at low revs, a little noisier, but the sound is better. The package does not contain a seal, it is necessary to buy a new one, the original can no longer be used.View Detail
A really good silencer, not too laud not to silent fitment was easy and fast i am really happy with the silencer i really recomend it!View Detail
The sound is a bit loud with a pattering feel. I thought it would be a little lower pitched but I'm a little disappointed. Installation was easy. I also feel like I lost a little bit of Torque.View Detail
[How is it used?
Gap forest road and mountain play
Was the one you received as per Image?
I had done my homework, but it was a lot smaller and lighter than I thought it would be (which is good because that was my goal).
Was the installation difficult?
The installation itself is not difficult, but there is BALI etc. inside the place where the insertion is originally tight.
I lightly treated it and hit it with plastic hammers to finally get it in the right position.
It's inexpensive and I personally find this level of work acceptable.
How was your experience with it?
Purchased with the expectation of weight reduction. The effect is as expected and you can feel the lightness around the rear anyway.
You can't tell much on the open road, but on Dirt you can feel the lightness.
It seems to be a little easier to turn at high rpm, but the difference is only about the same as Brush-Bo.
However, I don't feel that Torque has lost any weight, so I'm satisfied for weight reduction purposes.
[Was there anything that disappointed you?
I'm not happy with the sound quality, although I knew that.
The volume itself is not so much, but anyway the bursting sound is terrible and grating.
I had done a lot of research on Net beforehand and extended Baffle's Pipe by about 4cm.
This eliminates exhaust interference at the tail and lowers the volume to almost the same level as NORMAL.
In addition, the sound quality has been improved to a Gentle sound with a little more low-mid range than NORMAL.
Apart from the above, we also found some serious defects in the product.
The Restrictor is sandwiched between the Tail cone and the Silencer body.
The gap there is too Large and the Restrictor is not fixed.
So after a few dozen kilos, the spot welds on the Restrictor came off and it started to act up inside.
I put in an Objection to Manufacturer and got it replaced, but the replacement is in the same condition.
Not sure if it's a design phase issue or a ROD issue.
After you buy it, you need to check it and fill the gap with Washeretc. if there are many gaps.
Because of the dimensional tolerances and BALI problems during installation, the above weld peeling problems, etc.
Unfortunately, I can't recommend this product to anyone who doesn't have a certain amount of work sKill.
However, since it is the lightest Silencer currently on the market
I think it is a good product if you buy it knowing the above defects.View Detail
