The Catch Can Bottle ? Those are sold at major performance parts shops online, like JEGS, SUMMIT ( the 2 I know have it)
If you have the stock carburetors together with the stock air filter housing then this Crankcase Ventilation Bottle would be an improvement because although the stock carbs have within the stock air filter (factory air filter housing) provisions for the crankcase hoses to hook up, those factory provisions re direct crankcase saturated hot and oily fumes into your carburetors. not great.
If you use pod filters ( no factory air filter housing) then the right thing to do is to use one of these bottles (any brand you like, but a vented bottle) because your crankcase ventilation hoses would have no way to hook up to the pod filter units.
That would not be advisable anyway, ( hooking your crankcase hoses directly onto pod filters) you would not want to send hot, oily misty dirty saturated air into your carbs which need cool, clean flow of air.
By using this CR set up, I have no choice. Well, there are two other options. I would not recomend either.
One option would be to hang the hoses off the bottom of frame. That would allow moisture, dirt and grim into engine block. The engine releases hot saturated air through hoses but it also sucks in clean air, any air mass exiting block has to be replaced by air entering block.
So bare open hoses is not a good proposition.
The most common option used is just hooking breather filters to the hoses or engine block nipples. that is better than open hoses, off course, but not good enough.
The engine can expell saturated air and inhale cleaner air, that is for sure, but the oily mist is just spread outside the filter making a mess around it. The worst part of that filter hook up to end of hose is that the oily mist collects upon filter clogging it up, rendering it clogged up soon.
The Bottle has a baffle plate and the air filter is located away from direct spray, so mist collects and oil drips onto bottom of can, can which has a valve that allows emptying of bottle every few months, keeping filter in good condition for way more time. No need to take bottle off, quick release valve at bottom makes it as easy as opening your faucett.
