Just my 2 bobs worth, in 50od years of "tinkering:" with evil intent with various exhaust systems on motor cycles ,cars , hot rods ,and trucks I have rarely achieved a satisfactory result in sound or performance gains, exhaust design is a black art better left to the experts "homemade " exhausts and butchered stock systems almost always look and sound less than nice ,I reckon its better to save your pennies and then get a professional system or just do the Tors and cat box delete pipe and keep the stock system to refit at a later date , if required
