EDITED TWICE NOW TO FIX ALL MY MISTAKES
Ok I will try to answer a few questions on the
Angry Elf Engineering stacks.
Currently four sizes/styles all custom made.
#1 fits dang near all of the Stihls from the 026 up to the MS660 with a 2" OD.
#2 fits the MS880, 088, 084 and 3120, it also fits the 075/076 and the crazy WB carb that some of us have been playing with, it has an OD of 2.49"
#3 is for the Husqvrna 288, 281, 61, 66, 266 and some of the Pioneer models with a stock 288 elbow and has an OD of 2.25", the carb bolts are slightly offset.
#4 is for the Husky 2100 , 2101 and 298, it has an OD of 2.125"
We would be open to having other models produced based on demand.
We have all four of them with Unifilters as well as just the bare stack.
Search on Angry Elf in my store for pics (sorry no nudes).
We looked at both the K&N and unifilter when we started and went with unifilter because they are washable and oil able, and seem more suited to chainsaw abuse in milling, etc.
