Flowmaster or Dynomax?


I cant make up my damn mind!!!!Heres my problem,i want loud but not mind blowing rock concert loud!I also dont want stock.I was leaning towards flows then dynomax then back to flows.Ive never heard 80 series flows on thirdgen 2.8 so if anybody has any sound clips of the 80s on a 2.8 it would be appreciated.
Thanks
p.s i know you got em Mike!!!

I had an 86 Camaro with a 2.8 and a Super Turbo catback. With a gutted cat, it sounded OK. Definately loud. Dynomax tends to be on the quiet side though. For a 2.8, I recommend the Super Turbo.

I don't know about on a V6, but on the V8s the Flowmasters sound AWESOME, way better than the Dynomax in my opinion.

I would go with the Dynomax cat back.
I had that on my old 2.8 with a gutted cat. It sounded nice, and added a bit more power.
I had a friend with a Flowmaster on his 2.8 and it was loud, but sounded like a loud V6. It just didn't have a poweful sound. My 2.8 sounded like a a bigger engine at idle.
Had several people think it was a V8. I got the system for the LG4 and LO3 set up.
