Ram pipes?

What are the pros and cons of ram pipes on carbs? Do you use an air filter with a ram pipe, or does use of a ram pipe imply no air filter? I'm unsure whether fitting ram pipes to Harold is a good or bad idea. Comments please!

Bling-bling, IMHO. From what I've seen, they look cool, and maybe add a fraction to output. But no filter for any length of time spells T-R-O-U-B-L-E.
 
no filter for showing off, but put a filter over it when you go driving.

One of the supporting vendors ( su-filters.com ) makes custom air filters for SU carbs complete with integral "air horns".
 
As a mention here: The stock air filter "base" on the SU's has a curved "bell" contour to act as a "ram pipe" already built in. Just an FYI.
 
Yeah, they look good, but will allow dust, grains, dirt etc to get sucked into the carbs and pit your cylinder head, get in the plugs etc.
The racers use them because of the uninterupted flow direction, and they take their heads off more than I open the bonnet release catch.
 
Doc is correct - the stock air cleaners had their own built-in "ram" pipes....that's all you need...

....actually, if the air cleaners are setup properly with the little piece of rubber between the 2 cannisters, you're better off them than with rams by themselves as you're pulling cooler air into the carbs from up by the radiator....with rams by themselves,you're sucking hot air off the top of the exhaust.
