The CAPS question will probably need Joe to answer...

But the exhaust question: the cat is for smog, bypassing it won't effect anything upstream other than perhaps cause you to now have not enough back-pressure to idle as well. As long as the O2 sensor is on the downpipe (and working!), the carb will read the exhaust just fine.


I was thinking about punching it incase it's clogged. I hadn't thought about the lack of backpressure affecting it!

Good call. (I should'a ordered a friggen oxy sensor)
