I ordered a Moki 1.80 for my CapX and I am trying to decide which Bisson muffler to order. The 1180 which is the standard Pitts or the 1184 which is the 70 degree type. I remember reading an earlier post that mentioned trouble with the 1180 and I thought it said that the 1184 might work better. Has anyone tried the Bisson 1184 with a Moki 1.80? I would appreciate some help.


Thanks.
