I have not heard a FX45 with the stillen exhaust personally or even a sound clip so I can't be of any help there. As for performance, I would believe that no affect (good or bad) on low end torque would be noted but problably gains at the top would be relaized. Have not seen a dyno of the stillen on the 45 so no data there also.
