【OUTEX】Honeycomb Catalyzer Review

After all, Universal

The welding of the outer Flange section was messy,
ManufacturerThey were outside the published dimensions and did not fit delicately.
I was able to shave it down somewhat File and put it in.

The sound seems to have quieted down some … though,
It is best not to expect a muffling effect.

Improvement of the smell of the exhaust Gas is clearly effective, though,
It is no match for the OEMExhaust System catalyst.
It still smells even at RPMs that should have reached the reaction temperature.
We recommend that you purchase the product assuming a reduction of about half. View detail

Purchased for the purpose of reducing volume

[How is it used?
GPR's DECAT, an external Exhaust System When I installed the PIPE, the volume was too loud and bothersome, so I had to remove it. However, it was a waste not to use it, and because it did not contain a catalyst, I purchased it as an environmental measure and to reduce the volume.

Was the one you received as per Image?
I received a Straight Pipe product identical to the description and photo.

Was the installation difficult?
In my case, the exhaust pipe OD & phi;35, ID & phi;33 was just the right size to fit inside the pipe, but there was a bend in the bore diameter on the exhaust pipe side and a weld bead on the outside of the pipe on the product, so I had to use a plastic hammer to tap it in for insertion.
Instead, it is no longer necessary to drill a separate hole for screw fastening, etc., because it is no longer easy to pull out.

How was your experience with it?
As a result, the volume was just right, not too loud and not too quiet as OEMs.
Clean performance is unknown due to lack of measuring equipment.

As a reminder
In this case, it was an external exhaust system, so we have not checked whether it will be attached to the OEM or not.
Even if it is installed, it is not expected to be compliant with vehicle inspections, etc.

[Included Parts:were they on?
Not particularly

[Was there anything that disappointed you?
I was slightly concerned about the weld Bead, but I had no problems as a result.
In some cases, it may become an obstruction and may need to be scraped off. View detail

Let's mute it.

I used it for sound deadening purposes on my vfr750r Lady Bird 4in2in1. The length is 3cm longer and needs to be Cut. The thickness is 45 pi, which is just right. The catalytic converter part is 38 pie, so I used stainless wool to prevent it from rattling. The effect of the sound deadening is good because it became a little quieter. I don't have a machine to measure the sound level, so I am just guessing, but it might be just 99db. The smell of the exhaust gas seems to have been reduced by about half, so I think the purification performance is quite good. View detail

Exhaust System is 60.5 pi Asahina Tube Full Exhaust System.
Exhaust gas smells bad because of catalyst-less straight pipe. Naturally, it is not popular among fellow touring drivers. When I drive in front of them It stinks! It stings my eyes!" And.
I use it for my daily commute, but even after 15 minutes, my clothes, hair, and bag are covered with the smell of gas.
The Level was understandable within a radius of 2Meter.

By adding this catalyst, 、、、、 the smell is really reduced!
I feel 95% less! I'm not lying!

Since the catalyst itself is effective only after it is heated, it smells immediately after startup.
But after two minutes of driving, you'll be amazed. The smell of gas is gone.
I was really impressed with 、、、、 how comfortable it is not to smell the exhaust Gas.

It is not a Baffle and has almost no muffling effect.
Idling has only removed some of the cadence of the sound. (The volume remains the same.)

Power down is almost imperceptible.
However, it is definitely in resistance, so it should be falling numerically.
And yet it has a reliable deodorizing effect. It is wonderful.

I really, really recommend it to anyone who has a problem with exhaust Gas odor. It will make a drastic difference!
A little expensive, but considering the effect, it's a small price to pay! View detail

Installation is easy

When I first switched to the external exhaust system, I felt something was too loose and the lack of a catalyst bothered me, so I bought it, though it was a bit expensive.
I can't explain the specifics, but it felt good...no more explosions from the exhaust system, no more stalls and no more driving discomfort. View detail
