Fuiyo.. eh take pics and post as a DIY la. If you cut the hole in the resonator did you cover it with a breather or some sort of filter? Take pics share share la.
Hahaha! Lady Gaga indeed! The result of the test by Mightycarmods was performance. Filtration testing isn't really that a big deal imho since anything that gets sucked into the combustion chamber is gonna burn into crisp and break down into either nothing or carbon. Worst case scenario is you get a lot of carbon buildup and your engine oil gets real dirty real fast.
Don't say waste la. Think of it as long term investment. Sooner or later you're gonna drop in that turbo and/or stroke and/or balancing and/or PNP and/or close ratio gearbox mah
