The 2081 is an EFRA # 2081. The F0801 is a FEMCA pipe. They are similar in design (made by same company) but are two different pipes. The F0801 seems to perform a little better on the Argus Engine.
The EFRA 3033 pipe made by SH according to the dyno results is also an excellent pipe for the Argus Engines. These are also available thru any Argus dealer.
