my stock muffler was straight through, no restrictions.... DPF.... plenty of restrictions....my aftermarket muffler is the same .. straight through.... your delete pipe with stock muffler is going to be about the same as an aftermarket set up performance wise... technically the bigger aftermarket pipe will be better performance....you probably wouldn't be able to tell much except for the sound....just race him, and settle it that way...
