I've got the opportunity to buy a new Mazdaspeed Sports Sound Muffler kit from Japan and can't find any info on it at all apart from it was manufactured by Yumex. Does anyone know if its a particularly good system or would I be better buying something which was manufactured more recently ie Trust/Greddy.

I'm kinda leaning towards the MS one just for curiousity's sake but don't haven't heard any feedback on it.

Its just a street car by the way.

 

RB all the way. Their exhausts sound unbelievably amazing without being on the annoyingly loud level.

 

the mazdaspeed is pretty quiet and looks pretty stock , I'm sure its not cheap either and you could get more power with a header and custom catback (cheaper too)

 

Mazdaspeed stuff is really a waste of time and money to be importing into the USA.
They are slightly better than stock components, and don't expect huge gains versus other (i.e. BETTER) options available without all the import crap (i.e. shipping, fees, duties, etc.).
