i would like to start out by thanking all of you for the host of information you have provided since i bought my 2005 500r. i have read many of your opinoins about whether to get muzzy's or sarachu's. my question is the difference in price. obviously, with dual pipes, i imagine that will be one con of the 500r as far as my wallet is concerned. i tend to lean towards the muzzy's because of the way they scream. my second question is whether or not the muzzy's cans are larger than the sarachu's? i prefer big cans. there's a joke in there. anyway, with muzzy's will i need to rejet? these questions are in reference to slip-on's. thanks for the help. FULLTILT.
