I am trying to reduce the amount of noise created by my engine. I have a dual exhaust with Flowmaster mufflers, but the sound is still far too deep. are therer any noise suppressors that would quiet my engine to a soft rumble.

You could try adding a balance pipe right behind your collectors, where ever you can fit it, this will tone it down a bit and pick up some low end HP. To me it makes it sound like the stock early Z28s 60s - 70s.

I've never heard this one before. I've always tried to get mine as "deep" sounding as possible.
If you really want it quieter, swap out those flowmasters to a turbo type muffler. I heard they are quieter and produce more HP. The balance pipe would be a great idea too.
