This may sound silly, but what dual exhaust system comes with a stock 99 Ws6 Formula? Bought it used, so I don't know what brand it is. However, I do know it came off the lot with that exhaust. Pretty sure its either flowmaster or magnaflow...

No car came off the lot with a flowmaster or magnaflow exhaust. The dual exhaust system that came stock on a "99 WS6 formula would be "stock" exhaust.

No 4th gen Fbody came with dual exhaust...the manifolds run together into a Ypipe and then out a single pipe to the muffler, then out two exits. Not true dual exhaust. If you have two mufflers, its aftermarket and could be anything.
