3.2 with open exhaust?
I'll be doing some W2W next year and would like to run megaphones on my '84 euro 3.2 with ssi's.
The engine has a few other mild mods (964 cams) but is mostly stock.
Will this cause any mixture issues? Running lean?

My opinion, if it is still EFI, yes.
Are you running a chip and have you dynoed it for Air Fuel ratios?
If you are not running a chip, go to 911Chips.com and look at Motronics and get familure with the Fuel Quality Switch. This will alow you to richen the fuel if needed.
You should be ok up to about 5k rpm. Just past this and the flap in the air flow meter stalls out and the fueling is by predetermined amounts so there is not compensation for increased air flow.
Put it on a dyno to veryfy you A/F's.
Suggistion, 1.5" is a bit small for your motor.
