gsx1100F exhaust compatability

[LeoNine]

Question: Will an aftermarket secondhand 4 into 1 exhaust system currently fitted to a '91 UK model gsx1100f transfer and bolt straight onto my '95 model to replace its factory original 4 into 2? Further to that, will any rejetting be required? Hope one of you guys is in the know...

You should be good to go with that. I'd suggest installing a FP Stage 1 jet kit and a 5* ignition advancer but it's not completely necessary. The bike will run well with just backing the A/F screws out to 2.5 turns.
