I'd also add that there's also the appreciable weight saving associated with the aftermarket system and the binning of the 3.9kg cat - in addition to the fact, that it's also far more aesthetically pleasing. The main negative for me is the implications for emissions.The 15ftlbs of torque you gain with the full system isn’t a justification. It’s a fact. Same as it’s A fact you loose mid range when you delete the cat with a stock header.
