ok im gonna uprgrade my 50 series to a 40. i still have to insert a 4in piece so it will fit. but i was looking for the prices and which one do i want, the delta flow 40, or the original 40? thanks

I had DF 40's and reg 40s on my mustang and I would have to say the reg 40s. the DFs didn't drone signifigantly less and they sounded worse IMO. I took the DF's off and put my old 40's back on.

alright sounds good and they are about 20 bucks cheaper too
