Sorry i can understand the back pressure being ok for the motor and the extra flow causin harm but why would one of the pipes not be used? 2 header pipes one the other one has 2 the same why should flow very well. but lose low end and mid some what do to the extra cfm flow no or am i wrong???
I have alot time dealin with blown motors and if my knowledge serves me right that setup would yeild a better top end but short it in other areas.
