Yeah, they're all pretty much the exact same other than the oil thing. Just get whichever you can find the best deal on.

 

Best is debatable on the self contained vs the oil line units. the self contained v3 has that small amount of oil in it that it continuosly uses until you changes it. the oil fed ones are sucking from a 6qt supply of oil that is also cycled through the oil filter and gets changed out with the oil changes.

 

id rather change my oil once

 

Is it easy to change the oil on the V3?

 

the v3 comes with a 6inch attached stainless steel hose to drain the oil, and if you get it new they supply you with the first oil change .

 

a few ounces of continuoulsy used oil vs 6qts of filtered oil supply to suck from. pro's and cons to any and eveything. if self contained was the end all be all then all of their head units would be self contained. all turbos would be self contained too.

 

been running v1 for two years. no complaints loud and everyone can hear it.

 

v1 if you want to attract attention sounds like a jet plane pulling up anywhere. as far as tapping the oil pan, it seriously isn't that bad at ALL, despite the way it sounds
