I have a couple planes that have an exhaust pipe that looks like it is thread in to the muffler. It looks really nice and directs theexhaust away from the plane. I am new to rc so I don't know if this is normal or not. Iwant to put a new engine I have in a third plane. It comes with a muffler but no pipe is in the threaded outlet. Is there somewhere I can buy this exhaust pipe or is suppose to run with nothing. Please help me figure this out or give me suggestions on what else I can do. Thanks</p>

You need to tell us what engines you have?

I am using super tigre .61 for all three.

If you are missing the header that attaches to the engine, then you'll have to get a new one.

I have the header that goes between the engine and the muffler. But at the other end of the muffler my other planes has a ehaust pipe. Like a tail pipe on a car. Where can I buy this pipe that will fit or does anyone do something different at the outlet side of the muffler.

I've seen these on Super Tigers years ago. Don't remember who made them? They were by Dubro or someone like that. I don't think they are made any more?
