I just used a red scotchbrite to scuff them up then wiped them down with a rag and cleaner then primed them then a few coats of semigloss black.

It's impressive to say the least..

Well, I won't be able to make it. I don't have it insured yet and all I have done is break the cam in. I don't want to risk it going on a trip like that for its maiden voyage. I really have been working my butt off to try and make it but its not going to happen I think.

That looks great!

What kind of muffling does that rear can do? Is it straight through with glass packing, or?

[kumalaba]

great job!

Thanks! It is a semi straight through. Its made by a company called Aero and it is their turbine muffler. There are cutaway pics that you can find that show how it works.

great job!

Thank you! I finished it today and I'm dropping it off at my friends house right now to have him TIG weld it all together.

Hmm interesting. Can't see it working like they're claiming, but it does look nice.

If you decide you want some real muffling later on try the design below. Simple to build and works VERY well, but still leaves most of the low grunty sounds, and flows VERY well too.


It's just a chambered resonator without the packing and BIG (like 5/8" big) perforations in the inner tube and a rounded divider.

That is similar to the way my muffler is supposed to work but in your diagram you are essentially forcing the exhaust to go through the "baffles". Where as, on the Aero muffler I think the science is as the exhaust enters the muffler, some of the gasses expand then travel between the inner and outer skins and then are forced back through the perforations. In a similar fashion to the design you made.

That's my issue with the Aero design. If you don't force air through the baffling part, it's going to take the path of least resistance in my mind. But I'm not an engineer. Just a tinkerer who's read way too much stuff.

[gergorian]

I feel ya there. Lol

And there's a lot of thread like this I found from googling.

Nice Find! I see what they mean by the science behind it. Can't argue with that. I mainly went with them for the sound. I watched a bunch of vids with aero mufflers installed and they sound pretty good from what I could find.

[gergorian]

Exhaust is in!

So, I finished the exhaust. I just have one more hangar to make. I think it sounds a bit ricey so I may end up cutting this muffler off and putting a chambered muffler on. Let me know what you think.
