Hello,
A friend of mine has a 2011 (I believe) F150 with the 3.5l Eco boost engine. It has a Magnaflow aftermarket exhaust on it and seems to make a noise like when you are blowing over the top of a tube or straw. Its like a whistle type noise. It happens only when you are in the throttle, not towing or loaded, at about 60-70mph... When I road in it, it seems like its coming from the exhaust, is this just what the aftermarket systems sound like?
I don't think its from the engine.. anyone else have this?
Thanks.
