Tri-Z DG pipe, Xtreme or Racing(nationals)?

[Kintore]

I found this thread-
Link to thread (http://www.3wheelerworldforums.com/showthread.php?t=34942&highlight=TriZ+DG)
Its about the DG nationals pipe and Xtreme pipe. The question there didnt really get answered, which is better?
I am sort of leaning towards the nationals pipe though, because of DK description.
Who has a nationals pipe and what kinda gains did you get from it?
Also, who has the Xtreme and what kinda of gains did you get from that?
Who has tried both?
And are the pipes the same just with different coatings? I want to get the one with the most performance, the reason I ask is beacause DK descriptions are different.

And lasty, what kind would you chose?

I have the extreme on my Z. You dont gain much from these DG pipes. Pretty much for looks if you ask me. I have tried both pipes they did they same thing.

If they are the same pipes then I have 3 final questions. What kinda gains did you get granger? like low end mid and top end wise? did you have to rejet?
And also, I read somewhere yours started to rust 1 week, is that true?

I had the DG race pipe on mine first.It made a difference in the mid to top range.I just put the Xtreme on it.I am hoping to get some more bottom end.I havn'r run it yet.I also bought this one for looks.

I agree with you bubba. and yes my pipe for some odd reason started rusting the first week i had it on.:cry:

The clear finish burns off within ten minutes and if you let it sit in a cool climate it rusts. The National system on my T3 did this.
