The published IFMAR rules as of yet only require the INS box. I didn't find a requirement to use the 3 chamber pipe, but I do believe that at some point IFMAR will only approve the 3 chamber pipes in order to keep the noise down.

A black plastic cover that goes over the carburetor. It has two air inlet holes. The air filter goes inside it. It cuts down on the engine noise.

You use the same air filter as before. It goes inside the INS box. In terms of power, most people can't tell a difference. I have had some say it takes away about 1-2% of the horsepower. It isn't required in the USA, but most of the top drivers use them anyway. All the engines being made now are made in europe where they require the box.

Theres a section in the latest Racing Lines magazine on the 3 chamber pipes and how they`ll probably be a requirement in the future.....maybe this is where your friend got his info about them?

With the ever growing world and the same amount of land we are getting more and more crowded by the day. I welcome the fact that we are trying to cut down noise on things in the world. But to start with nitro racing is kinda rediculous.

I would rather see , cars , airplanes and air handling / heater units much more quiet. I walk outside my house only to hear buzzing units surrounding me and the highway beyond that making a constant buzz till late at night.

Inside my house , my computer buzzes , fridge and even video game systems now and even my LCD TV has a fan that buzzes.

It can certainly drive you crazy. Sometimes when you catch it right and everything is off you find a nice peacful quiet sound. But really there are many more things that make sound, and a lot more continously not sure why they want to start here and with racing. Which is what you go for.

I could only imagine going to an F1 race to hear very quiet and muffled sounds of puffing and chugging , rather than insane banshee cries from the motor.

At the moment the move to 3 chamber and INS boxes is only affecting the 21 on road class. I feel it will be a while before we see it affect the 12 classes. currently no one even makes an INS that will fit a 12. the 21 INS boxes are to large to fit on a 12 they crash the head.

I heard earlier this year about 4 months ago that 3 chamber pipe was require for 1/8 scale buggy only and for 1/8 scale on road it would be require in the near future for the USA.As for Europe its already require and INS box also. I thought the INS box was require this year in the USA for some big races for 1/8 scale on road and will be require for the new season. As for club racing I don't know if they require the INS box to be use. Also I seen that .21 exhuast companies for on road are making 3 chamber pipes now and not many making any new 2 chamber pipes. All I know they been targeting 1/8 scale class only to quiet the cars down a little.

Talking INS + 3 chamber

We run 3 chamber pipes + INS Box more than 2 years and the primary reason is noise. The top speed hurts a little but there is benefit to it. The idle is more stable and the bottom end is much better compared to 2 chamber pipes. A give and take situation, once you ger used to it, there is no problem.

Right now I have no problem running a INS Box or 3 chamber pipe or even running both. The last two months I been running with an INS Box in my MRX4 with no problem. I couldn't even feel the difference between INS Box and the normal air filter while I was driving. Just recently I purchase a JP Racing EFRA 2031 strengthened pipe which is a 3 chamber because the pipe that I have now is all beat up and its about 3 years old.
