  Best sounding exhaust for the money!
By on 6/27/2014
I bought these mufflers a month ago and i couldn't be any happier with them! I used to have flowmaser super 40's, but due to the horrible highway drone i threw those away and bought these. These are nice and tame at idle, same as the flows midrange, but no drone. and at wide open throttle they are super loud and raspy! they are perfect. Dynomax is underrated!!!!

Yes, I would recommend this item to a friend!
