True , the water in the tail pipe comment , there is a great deal of moisture in the atmosphere , for every ten gallons of fuel burned a gallon of water is produced. Much of this water is discharged quickly as the exhaust gases flow through the tubing , some collects and is seen as drips out the tail pipe. Exhaust systems have a relatively short life span compared to the rest of the car due to this.
My 88 had the whizzy 4.2 / Carter feedback carb setup on it , yup , I bypassed it and used a rebuilt 81 CJ carb for a while. Yes I removed all of the pulse air rubbish , re-configured the vacuum hoses n' stuff , retaining the tac-vac hot air ducting for cold start / warm up. It ran better afterwards but was a pain to do cleanly , perhaps I went overboard , removing the entire underhood wiring harness , surgically removing all traces of the 80's emissions stuff , then re-bundling the harness neatly so an un trained eye couldnt tell. It's not easy to do , there are many splices , runs of resistance wire , relays and various gadgets to confuse the unwary. A wiring diagram and above average understanding of electrical systems is recomended before attempting to do what I did. Would I want to do it again ? , nope , as old school as I am , efi is MUCH easier to work with and runs so much better.
