For those of you that have Smithys just need to ask a question regarding which way around they go. I know they are marked with "inlet" on them, that would go to the incoming gas from the motor, however the louvers are pointing away from the incoming gas, I take it that its normal? If you turn it around so the louvers "catch" the gas what is likely to happen? I have the 2" pipe ones they seem very restictive when you look through them... I take it thats the design..
