flowmaster 40 series Are these as bad as far as restriction goes as the 80 series? Does anyone have any testing on these in an H pipe setup? Im considering replacing my current dynomax pro flow mufflers with flowmaster 40's and want to know if I stand to gain or loose.
And to the OP: the 40 and 44 series mufflers are nowhere near as bad as the crossflow.

not to worried about clearance. I sectioned the floor beneath the rear seats and gained almost 4 inches of clearance, Right now Im running the full size dynomax pro flow (bigger than flowmasters) and I have better clearance than I did with a y pipe.

I have the Magnaflow Catalytic Converter 45420, I purchased it direct here. Magnaflow Catalytic Converter 45420, I have no comlaints with this cat I passed emissions and got not engine code errors so Im happy. You would not believe what the dealer wanted to charge me for this thing. Definately buy online and put it on your self its way cheaper.

My wife has a deltaflow 40 on her Durango and it sounds good and you can hear it from down the street, although its a truckish sound. I have heard another 40 series on a H/C Z28 dumped straight off the y and that **** sounded badass.
