DTT and FatCat 2-1...Any reversion issues?
 

I am in the process of installing a DTT TCFI III with WEGO IIID and have a question about the D&D FatCat 2-1 exhaust. The WEGO instructions note that open pipes will have an exhaust reversion and cause an erroneous AFR condition. Has anybody had this problem with the FatCat 2-1? If so, do I have to fabricate the exhaust mods referenced in the directions?

Regards,
