Zonda thats the perfect pipe for the 5 port from Dynamite. I used the same 1. If you have any questions just come here and anyone will help you out. The 5 port is awesome for buggy or truggy. Buggy I suggest a small carb restricter carbon shoes w/1.0 springs, truggy stock restricter or a tad smaller alum shoes w/1.1 springs.
