Flowmaster 40 Series Muffler - 2.25 Offset IN / 2.25 Offset OUT - Aggressive Sound is rated 3.0 out of 5 by 1.
Rated 3 out of 5 by from not really aggressive. . I have these on my 96 impala ss ...they sound nice on startup but to say aggressive, should say some along the lines of moderate. If you are expecting these to sound close to the original 40 series "like I did" you're wrong . Almost night and day.
