Yes they are the oval or rounded flows. Are the square ones louder or something? Even if the O/R H doesnt make it "crazy" loud I think it will make it louder and deeper sounding. And the HP gains will be nice.

Hate to tell you but there will not be any hp gains. A friend of mine actually got slower E.T/MPH when he replaced the stock axlebacks with flowmaster A/T. There may have been something wrong with the flows. He got them from another person. At the1/8 mile track he and another friend of our who has a S197 were getting constant 8.5 at 85MPH. Both drivers had drag radials. Next time at the track, my friend put on flows and was only getting 9.1 at 79 to 80 our other friend was still getting 8.5 at 85
Does anyone have a sound clip of the flows showing the difference between the 40 and 50 series ab's. Was considering going to the 40 series but want to hear the difference first.
