bro,we discuss about this before.the thread is still around here somewhere.4-2-1
is for low to mid while 4-1 is for high end.meaning the first is for pick-up n mid-range
pull while the later is for top end power.in extractor,look for mandrel bent pipe
cos the gas can flow faster n if u got more money,look for a merge collector then
Y collector.merge collector exhaust tend to be more expensive cos difficult to make but
flow a lot better then Y collector.check out those jasma extractor.most of it come
with merge collector n all construct using mandrel bent tubing.
