I've found that the stock intake system PAST the air filter is the problem... The actual filter itself is bloody good, but the piping past there is horribly restrictive, especially if you're changing turbos, hybrids and the like...
DTs with a cone filter on the stock intake just sound TRAGIC, that typical low bellow the entire time, and it sounds jank... Haven't heard a HDI, but I'm going to assume they also sound jank, unless you've got a piece of 3" pipe going down to the turbo and a mahoosive filter on the end, they tend to just sound crap as it muffles out the compressor noise, but accentuates the typical induction drone...
