PowerPipe-SC Info= air in 1.5x6=9+3= 12 divided by 2.25 air restriction = 5.33
Stock Exhaust= air in 1.5x6=9+2= 11 divided by 2.00 air restriction= 5.50

PowerPipe-DC
The air flow test was on the single connection,here is the duels even better yet! 1.5X6=9+3=12 divided by 4.5 air restriction= 2.6 remember lower # means less air flow restriction.

The Materials are .045 aluminized steel, set on 1/2" flanges with 2 1/4 output connection. Hope this helps. Don
