Firstly, thanks for your reply. I've admired your responses to other members that's why I posed the question to you. You obviously have vastly superior knowledge in this area than I do. BTW, I never mentioned that my car was a 99 se sport not an SVT.When the exhaust shop removed my original exhaust I did notice that it was made using crush bends. However, unlike the new system they installed, The bends showed an obvious decrease in diameter at all the bends. It had "clamp-like" marks on all of the bends. I did a bit of research last night and noticed several sources mentioning that the oe system on many cars is produced using crush bends. Also, that a good crush bent can be better than a poor mandrel bend if the mandrel bend is welded anything but perfectly flush and without any holes in the weld. In my particular situation the bends not not look to diminish in diameter at all compared to the factory system. Honestly, I've noticed a significant increase especially in the mid-range.Also the tires are willing to spin much easier from a start. The car reminds me more of another car I own A 2002 Maxima se 6 speed. Of course, that car is faster than any contour svt or not and in refinement is like comparing a dinner a Denny's to a steak dinner at Burns. Thanks again for your response.
