aerospeed mufflers, are they any good or what?

thanks Brandon

 

When I first got my arospeed muffler, it was my first exhaust mod. The sound did not increase much at all just a slight deep sound. After the y-pipe it got louder, but still deep. Now, after my b-pipe it is extremely loud and somewhat annoying. It will not sound like a honda, v-6 sound is quieter and deeper anyway. With just the muffler I felt a seat of the pants increase in hp in the upper rev range, but not much at all.
