power core 2 turbine core 2

[kenney]

hi all. I ordered a power core 2 silincer for my bike from the dealer. they tossed it in a bag and when i got home i noticed that it was a turbine core 2 instead. is there any diffrence between them other than the spark arrestor. any changes in power?
thanks

I have a powercore and a turbinecore11 for my 310 and I cannot tell the difference in power or delivery between the two. I leave the TCll on all the time

You got a good deal then. The Turbinecore is $30 more! The power is supposed to be pretty similar.
