    hi lads, just wondering if anyone has tried, OR successfully carried out a "GRONK" MOD on a Harley Dyna, mine,s the 2007 model, is there a Cat. Converter in there , or can both baffles be taken out and drilled with larger holes, one for the "heads" surely.!!!:34:

    Shouldn't be cats but I wouldn't drill out the baffles, it sounds terrible but ONLY YOU will like it only after it is done because it's done. Do it the right way and replace with slipons.
