Question for Fi exhaust owners...

[ibjesster2002]

I just ordered my Fi set up and am very excited to get some aggressive tones goin. As these are, let's say, "unique" sounding engines (firing order and all) I am going to play with some things and see if I cant tweak some different notes out of this one system.

Can anyone with this set up just get me a couple measurements?
Looking for:
- Pipe diameter
- Length of "tip pipe" (See pic)

Thanks in advance. Should be a fun little experiment.
