[SWEET7T]

I have a stock 327 with a 2bbl carb. (Plan on big cam and 4bbl)
I have the stock manifolds (2.25"outlets), then go to 2.5" all the way out. I'm running a 'true' dual (no x-over) with 50-series Flowmasters. The exhaust kinda resonates a little above idle (kinda annoying when dragging main), but it doesn't get all too much louder at upper RPM than it does at lower (just sounds more raspy). I don't hear it much at all on the highway running 80 turning 3000, prob due to road/wind/old truck vibration noise.
