Dayum, gimme your number. Your gonna be a refference. Did you see the car at 66 ? Thanx though. It takes a while to make the kits, and it's nice when someone really appretiates it. THe primaries are 1 5/8 into 2.5 crossover. The DP and inlet tube are 3in. The inlet is SS 304 though. I ran MS with mine and won't use it anymore for an inlet. Scaly rust buildup even though no water.
