Conversation Between FordmanShane and HIO Silver

You've got a lead on 3-inch Spiral Flows? IMO, a dual 3-inch exhaust is oversized for the RPM range of these trucks. A single-3-inch fed by two, 2.5- or 2.25 inch tubing is okay. Ya need low RPM torque and dual 3s doesn't provide enough backpressure.

Yo Silver! I have a chance to get 2 3 inch moroso's for the price of one! would you recommend 3 inch!?
