and it doesn'y sound even close to my friends MX. He doesn't have a air intake either only mods is an exhaust. Well he said its a better engine in his mx or something like that but I forgot what he said. So is it maybe the BP or BPT swap that makes the car sound really low and a loud growl because I want to get this intake for my MX=

will this help with the sound too? what else makes the mx sound like that? ex:headers ect.
