Theoretically yes, but not enough to notice. You would get more benefit from removing the roughly 30 pounds than from eliminating the restriction in the system. All tolled, it could be less than 1/4 mpg. XXXXXXXXXXXXXXXXXXXXXXXXXXXX This question can not be answered in this forum as it is an illegal act. The Federal Government mandates that the emission system on an automobile is Not to be altered or removed from a vehicle and is punishable with a fine or imprisonment.
