I am going to be getting a banshee in the near future and was wondering which company does the best port work.? I have heard of A&S , Trinity, CT and Dukas I think. I would like to get either T5's or CPI pipes. The kind of riding I do is mainly the dunes. I would like the powerband to be a little less on/off. Trinity has what they call MX/TT porting and they claim it's the bomb. Just wondering if any of you have this type of porting and if you like it. Would T5's or CPI pipes work well with this type of porting? Any info on this will be greatly appreciated. Thanks

 

for the pipes those 2 seem to be the popular choice for sure
porting my dad has the duncan racing national pipe and porting kit
he likes it a lot
it adds more power and is easier to ride because the on/off powerband is smoothed out a bit with more midrange power
good luck with your decision latr
