can i remove mine and run it without any thing at all? or should i get hold of a recircultaing one?

i know people on here and run them quite happily without, but does it shorten turbo life span etc???

prob an age old post but just curious, as i'm gonna remove mine from my saff 4x4, (cos i love the chatter) and wondering whether i can just blank off the pipes from the intercooler and the turbo to filter

also does it make it less laggy or more???

cheers
