yeah these mufflers are cool as shit if you have all factory exhaust (cat, header blablabla) it's almost silent until you get on it a little bit. if you have a header and no cat or resonator it is still pretty quiet, but you can hear it fairly loud when you get on it. all in all it's a good muffler. looks crazy up under any car and doesn't sound like a fart can.
glws. if i ever get exhaust i will seriously consider this one as it's not annoying like most everything else and is very cheap.
