Sorry if this is beating a dead horse but I don't want to spend hours searching. I have the Blastin Bobs Magnaflow glass pack reso delete kit coming. The only difference I can see between those and the plain glass pack is that the MF has perforated baffles, and maybe a deeper tone. I wanted to retain some back pressure. All I'm looking for is a lower exhaust note. If and when I decide on a air filter upgrade or CAI whats the opinions on the computer adjusting itself to such minor changes? Don't know anything about these tuners. I'm a old school Harley guy used to having carbs. Thanks
