stupid... yes Mugen is awesome...so...an exhaust as long as its well constructed is just that. a well constructed exhaust and Mugen isnt the "best" performer out of all the companies offered. to drop almost a grand on a catback exhaust is ridiculous. you can get a RACE titanium built exhaust for the same price...and street parts are never the same as race only parts. a Mugen exhaust is badass yes. worth the money? depends if you think bragging rights of owning one is worth a $1000.
