Any testing done on FMF "Turbine Core" products verses Pro Circuit "Spark Arrester" units (has an evergreen tree on the label)?

It appears both use interior baffles and according to Dennis Kirk PC has a "clog free, maintenance-free design". Does this mean no repacking? both websites are useless

The real question: Are these units quieter and is there a perfomance gain over my old Power Core straight through unit?

Personally, stay away from the FMF units. You have to cut the rivets out to get the core out of the unit and then re-revit the core back in. Really something that they could have used screws to do the same thing like the endcaps.

Yes you still have to repack them!
