I am going to purchase a new system for my car, it will be a cat back system however I dont know if I should go with magnaflo or flowmaster. Please if anyone has sound clips or know of a good difference please let me know... I would be going with something quiet....(ok quieter) then what I have now and that is bullet mufflers.....so anything should be queiter... I am not looking for something loud as for the wife willnot ride in the car with me right now... (gives her a headache... or so she says )
