Hi Needing help on installing a exhaust no my TP P40E/Saito 100. First time using this type of exhaust.
1. What is the extra nipple for on the exhaust?
2. Is this the proper way to mount?
Bought this exhaust used from RCU market add It was listed to fit my Saito 100.
Thanks for the Help.

Hi,
The extra nipple on the exhaust is a preasure outlet to preasurize the tank. OOPs Isee now there are two, I would reomve one and peplace it with a smallsame thread bolt with a bit of locktight to secure it. I did notice missing bolts on the motor install. That is not a good idea, you need four to dispurse the load to the lugs evenly.
Do check for proper side and downthrust if required by your plane's instructions. Good luck.

Keleo exhaust systems are very cool items, and will give you a very unique sound when the engine is running.

By your pictures you do have the exhaust mounted correctly. The extra nipple on the bottom of the muffler is to allow fuel to drain out of the muffler when you fill it. When these are new they come with a short piece of fuel line has a plug in it. This plugs to the bottom nipple and is routed outside of the cowl. For normal use the plug is inserted in this small piece of line. But when you fuel the plane the plug is removed so that fuel can exit out of the muffler when you fill it. Otherwise the muffler will fill with fuel and make it difficult to start your engine, or cause hydo-lock.

To duplicate the part that ships with the muffler all you need is fuel line and a plug. plug the fuel line into the tap on the muffler and route it outside of your cowl. Then for normal flying insert the plug into the line. Remove the plug to fuel. If you don't have something you can make a plug out of you can order them Tower. http://www3.towerhobbies.com/cgi-bin...XK138&P=ML

Only the back two holes matched up I need to mark and drill the front two. Also need to notch the motor mount about a 1/4" to get the motor to the proper location. Thanks

RcKen Thanks.

Ken is correct. That extra nipple is a "Spit Valve"

I had one of the original prototypes of that muffler (before the Spit valve) and oil would collect in that area. So just connect a piece of fuel line to it and vent it out of the cowl

Be cautious Notching the motor mount. You can but it depends where the notch is as it may weaken the mount. Disreguard what I said about plugging the extra nipple.
RcKen has it right. He has a lot more experience than I because he is a lot Ol..... oh never mind

Thanks MinnFiyer OzMo I will be notching the web on the sides. Thanks
