I'm about to buy the SEE from Maxxfab, and i wanted to be be informed before i do. I would like to know if the resonator has any restriction on it at all. If it does and i order the SEE without one, how tough is it to add one later? And the reverse, if i order a SEE w/ resonator how tough is it to remove it? Im also concerned about spitting flames. I know just the 3" pipe on the SEE will have flames, but will that stop with the resonator? I dont wanna set shit on fire when im dynoing and crap as cool as that would be though! Oh! and also! I read somewhere here there is a bottle neck in the exhaust system. Im going to get the 3" o2 houseing as well. Is there still going to be a bottle neck i will have to remove?
