flowmaster giver it a much better sound in my opinon iv had both on my 95 4.3 tbi

Did you like your flowmaster or Dynomax muffler better? ---

ah ok, I was going to say I have 2.5" piping on my truck and its NA.

Its actually 3" pipe , with a 2 1/2 inch tip. I was told the tip being smaller helps the flow. I cant wait to install the electric cutout ( so the turbo sound shines through :) ).

Its stock right now. I have a LOT of parts , it will get a rebuild this summer.

Thanks for the nice comment ---

doesn't sound bad but how come you went with 2.5" piping instead of 3"?

I think it sounds good for a 6 cylinder ;) ---
