Default Hardcoated pipes?

Hi
Im just curious why they don't make the pipes for on-road hardcoated.
I don't really know why they keep making these polished pipes what so ever...

Hardcoated pipes are easier to clean, they are tougher and more durable.

Please tell me why and why not

I have always wondered if these coatings effect the performance of the pipe. These coatings are to some degree effecting the sound waves that travel through the pipe as well as the inner temperature of the pipe. All of these factors if I'm correct will effect performance.

The resonance will be increased because of the harder surface area.
The soundwaves will be absorbed less by the pipe which makes for better performance.

Looks nice!

Is it as easy to clean as for exampel the JP-serie pipes?

The surface looks like one of those old black boards they had in schools like a decade ago

I like to keep my car clean and the polished pipes is impossible to get clean after a run, stuff burn in to the material. The whole car except the pipe is clean, and i hate it

I did the anti freeze in a crock pot last weekend on my polished 9901 and header and it worked like a champ!!! Looks new.

Ive heard of this recently too - as far as I know, you just boil the pipe and header in some radiator coolant for a few hours and it comes out looking brand new - am I correct?

Carbon Off works like a champ just make sure you wear gloves.

Default Crock Pot Method

Fill the crock pot with full strength anti-freeze coolant until the pipes are fully submerged. Put the crock pot on low and put the lid on. Let the pipe cook on low overnight. The next day remove pipes and wash with clean water. If there are afew stubborn spots do it again after brushing them with a tooth brush. Carbon off is also a great product, but I prefer the anti-freeze method becuase it helps to remove the carbon deposits inside the pipe as well.

That crock pot really shouldn't be used for cooking after that. The anti-freeze is also reusable for cleaning pipes again and again. Just remember the stuff is toxic, and the fumes are as well.

Radiator coolant do have additives to protect your aluminium radiator from being attacked or corroding.
Therefore these coolants are pretty easy on your pipe.

Nevertheless, no pipe will look like new after you cleaned it, no matter what you use.

i use the carbon off, it works fine too. the fumes are quite strong. do recommend to use it in a well ventilated area. however, the stubborn stain is required to brush.
kyosho has a spray that is used to spray on the pipe, it will make the pipe non-stickable to dirt. anyone knows what it is?

As an engine builder for over 40 years I can tell you both you hit the nail
right on the head. Hard coated exspansion chambers on 2 cycle engines
always make more horsepower & make it easier to control where you want
that power in the RPM band.

GRP used to make a hard coated pipe for their Ninja line of motors. I loved it.
