My car is 200 miles away in hibernation or I would have done that for you. I have dual flowmasters on my 225 f-BBL/clifford headers and it sounds good!
Spoke too soon...Hear is one of my 17-second blasts down the quarter mile. This was a semi-final round at the car club challenge at Pacific Raceways (representing team Mopar). Not my best moment as I was on the brakes way too late.
Edit: Just a taste of what it sounds like, sorry I don't have anything closer to the car.
