I was charged $9.99 for shipping even though the ad stated free shipping...i was refunded $9.99 BUT i still paid tax on that $9.99 that i was not refunded. Other than that everything was all good...the megan racing muffler looks and sounds great!!! I wanted a muffler that wasnt obnoxiously loud but louder than stock and thats exactly what i got....AND the construction of the muffler is definitely good quality!!
