A buddy of mine had flowmaster 40's with VS cam. The car was loud to begin with but riding with the flowmasters made me go nuts. Drone so bad and sounded awful, way to loud and gave me a headache. Borla would be the way to go for a grand prix, but a little pricey. Flowmaster > Magnaflow > Borla
if people say flowmasters drone they are not doing their due homework...they dont all drone only some do.

i hope all those people that think there 3800's sound so good with straight pipes flowmasters or whatever know there's a difference between sounding good, and sounding loud and/or droney... anyone who thinks there 3800 sounds good with straight pipes or flowmasters all i can say is you must have never owned a v8.. and another thing, whats the point of having exhaust if your car is stock and/or not fast if its a Grand Prix 3800
