Hi Pawel,
I am using 40:1 on synthetic, but 50:1 should be OK.

All....Pic attached of my DL on a KS tuned pipe...adds 400 rpm..highly recommended!

Cheers

Hi Earle, i got the pipe and header from KS in germany, the pipe is model number 1060-4B

I bought one of the kits for my airframe (EF yak), No.551 i think, and also went for their own mounting system...as per

You need to make sure the length of the system is correct when you put it together, to make sure it performs at the right rpm, it comes with all the instructions on how to do this anyway. I did not need to change the length of mine as it was perfect for my rpm's (7000). Actually it was 7000, its now 7400 on a mejzlik 23 x 8 after i added the pipe.

If your ordering for the DL, just ask for the fitment for a DA50, as they are identical.

Regards
