I just recently purchased the grp .21 tuned motor, what is the best pipe, I have a JP-1, an RB-2045 (AWESOME PIPE),I have 2 diffrent headers 92 mm 98 mm,
I want to get the low end run up to a triple but still have some nice top end.
any help would be appreciated.

The glowplug chart you have is the US one. The OS Japan site shows P3, P4, P6, P7 and P8 in the turbo version.

If you bought it in the US or AUS it will come with the 2053 pipe with short manifold, i got mine from EU and it came with the 3009 pipe and long manifold.

At $309 it's probably coming from Hong Kong. One of those RC-Mart type places, I would assume.

So a p3 ultra hot is hotter then a p4 super hot?

Semple 07-31-2008 07:49 PM

P3 is their hottest.
