Message	but whether the 3" is tapered to 2.5" or remains 3" throughout does not matter? In that case wont you want to taper it back to 2.5"? That way velocity of the fluid increases, and with that back pressure decrease? Or do you recommend full 3", if so can you please explain again why (I've read through what you said, but still don't quite get it) Thanks ___________________________________________________________________________ There was a time where I wasn't sure whether the Z would be the right kinda car for me, that is till I saw this one morning... ...Yup. I drive a Z now.
