Re: muffler diameter on a std. 4age & mandrel question

I'm pretty sure that the std pipe diameter is 1.5 or 1 3/4 inches. Yes a 2-inch system will be better, you 'may' notice a slight drop in low rev torque, but that is unlikely. Mandrel bends are best as this process (mandrel) ensures that the pipe remains the same diameter throughout the entire bend. Other bending reduces / crushes the diameter of the pipe in the bend, thus reducing the flow through the bend.
