why? while its always good to relieve some stress from the backpressure of intake and exhaust, its the same idea as putting 3 1/2" pipes on a car with no mods done to it... a car works off a certain amount of back pressure... and in cleaning it up TOO much, you can actually cause more problems than you are fixing... just my observations from the past
