Power Silent Oval Exhaust System (Japanese Government Certification)

I bore up to the Carburetor Vehicles of APE 50 to 80 cc of HYPERSStage, so I searched for quiet exhaust sounds and purchased the same SP Mukawa product as well.
APE seems to be a bit too big Silencer Size, but the Oval shape is cool, emblems are moderate, the exhaust gas pipe handling is relaxed, the Compact Engine around looks a little Large Looking individually Large I like it.
Large caution when crossing over the loose curbs.
There is also low speed Torque also for performance because Exhaust pipe is long or thin, but there is also a growth at high speed, low rotation is quiet and high rotation feels like a perfectly good individual personally at a reasonable volume.
Wearing Oil cooler, I was wearing this Exhaust System for about 3 years, but because of the complicated structure of this Exhaust System, regardless of the season, the oil temperature was over 100 ° C in about 30 minutes of normal running on the flow , After that it became hot and sluggish, so we did not go far.
Although I tried various things such as setting carburetor, I changed alternately a few times to the straight type muffler which I had originally had, recently the oil temperature rise clearly gentle, I changed the oil temperature and changed it.
I do not know because it is not a measured translation, but slow speed Torque, the increase in speed of high rotation is disappointing because this product is more comfortable.
50 FI, 100 for STD Vehicle, which is unavoidable..
Although I still owned for over 10 years, I was a beginner and worked all by myself so it may be an individual difference Large but I posted it for someone's reference.

I bought and installed a beautiful one on CYGNUSX3 with 7000km on Yahoo! The sound is quiet and good.
At the time of SP Tadao, I tended to feel that the sound was a little high and rushed to skip, but this Exhaust System was bad.
If I were to say, I would feel quiet and inadequate, but Axel is also very modest and does not feel rushed.
However, I think that the growth at the high RPM is still a little short. In general, I think it is a very good balance exhaust system.

The shine of the Stainless Steel is beautiful in appearance and I like the style of the Oval Exhaust System best. The sound of the sound is a little lower than NORMAL and it is comfortable and accelerates to high revolution without stress.

Installation was not easy, but it took about 30-40 minutes
In the removal of the normal muffler, the fixed bolt of the M14 is stiff, so the long Wrench and Lubrication Spray would be a good idea
Installation is Smooth if you follow the instruction manual

The volume is as quiet as NORMAL, so it's not a problem in a residential area in the morning
The sound quality is more subdued than the NORMAL, and it's not too noisy even under acceleration

It's quiet for a pretty sporty look, so if you're looking for something quiet while focusing on looks, this is the one for you may be perfect for this
On the other hand, it is not suitable for those who want a certain amount of volume

CROSSCUB is 60 km / It is hard to raise engine rotation per h. I could not enjoy imaichi running with a sound that looks like a clogged exhaust. I changed my Exhaust System, perhaps it would be better, but I was worried that the exhaust sound was absolutely bad, but I found this item.

As the name implies, the Power Silent Oval Exhaust System is an exhaust system that combines power up and quietness. Engine Torque itself is the same as NORMAL, but because of the better exhaustion of the Exhaust System, it makes it easier to run fast flowing Bypass, etc. without Stress until high revolution, while giving a good crisp sound of the Veyen Was.

And it is noteworthy that the quietness of the exhaust sound. I purchased MORIWAKISlip-on SilencerMX back to the OEM without being able to withstand the Level saying that such a noisy though it is approved by the government, but this is genuineness quietness. Although it is truly a little bigger than OEM, it can be likable with calm sound without intimidating feeling.

As its name suggests, it is an elliptical Exhaust System that looks as if it looks Large from the side, but it does not jump out laterally as it looks from behind and it fits in the Compact.

When installing Axle Shaft's Nut (M19) Rear Suspension Top Nut (Replace M14 Cap Nut with attached M21Nut) Exhaust pipe installation Nut (M12) Since it is necessary to remove and reinstall it, Torque wrench is indispensable to prevent over tightening. However, when using Torque wrench of Box wrench type, if you do not use Long Type only for M21, you can not tighten up to reach deep and be careful. Spanner type may be better.

Others, exhaust gas from two split Exhaust pipe joints Heat resistant Liquid Gasket to prevent leakage, Stainless Steel Band joining Exhaust pipe and Exhaust System Bolt to prevent burn-in Rib Ten Grease, If you do not do it, you will regret it.
