fmf silencer ?

[gavnshel]

what is the main difference between the power core and turbine core is it only the green sticker issue or do you lose performance one to another thanks for your help

yep, just spark arrestor vs. no spark arrestor. I have a powercore, but never ran a turbine core before. i would think the turbine would be a lil bit more restrictive due to the arrestor

yeah the turbine core is made to be restrictive. they say i has the same power but i couldnt imagine it.

I have uploaded a very simple diagram of the (2) pipes. I have both, (2) Power cores on the lt250r's and a Turbine core on our KDX200 trail bike that has been street legaled. The difference in restriction is not much if any. The only thing different is that the flow of the exhaust is not straight through. The performance gain you get from an aftermarket pipe will be about 99% from the head pipe and about 1% from the s/a.

You will also find that you will get a large weight advantage by removing the stock pipe and silencer. I believe when we weighed our stock pipe and silencer it weighed about 28#s and the new fmf weighed about 14#s.
