I have a stock Pitts S2B exhaust that is modified for a smoke system that I would like to sell. Replaced with a Sky Dynamics system is the reason for selling. System has 876 hours on it. In excellent shape.

If interested make me an offer.

Hi George,

I have a S-2B and was looking for a 6 into 1 exhaust when I stumbled onto your ad.

Are you happy with the Sky Dynamics system and can you notice an improvement?

Thanks for your time,

Dave

I am happy with the exhaust. I was told by Sky Dynamics that the stock IO-540 with stock exhaust would dyno at around 235 HP. Putting the SD on boost the HP up to 260. You can definitely feel the difference. Vertical is better plus speeds seem to come quicker between maneuvers. Only draw back I have noticed is that it is louder inside the airplane. I can live with that for the better performance.

It does require a 337 to put it on and some FSDO's if that are not familiar with it may give you a hard time. Also requires quite a bit of modifications, re-routing hoses etc. Also the cowl flap door will have to be modified.

I don't regret doing it at all. I did end up spending more than I wanted. Exhaust was 2300 and required 25 hours labor and parts. I think you can count on 5000 by the time you get someone to do the 337 and labor.

Johnny White is a good one to talk to about it also. He has it on his S2C. He told me when I started looking into it that for the money it would be the best modification I could do to increase performance.

If I can help you get the 337 I will. The mechanic that put mine on has a friend in the Jackson, TN FSDO that pushed it right through.

Hope this helps

Here's a test I did after the original exhaust system posting. My stock S-2B up against a S-2C with a 6 into 1 exhaust.

Remember, the S-2C is suppose to have less drag than the S-2B, the Claw prop is suppose to out perform the 2 blade aluminum Hartzell and the 6 into 1 is a large boost in HP.
