i have eisenmann race mufflers...how much louder would it be with the RISS RACING X PIPE WITH HFC ?

also might have opportunity to swap the Eisenmann RACE for the Eisenmann SPORT...then match that with the same X pipe.

any input on noise levels? x pipe has HFC but no resonators

looking for hp gains but not so so loud
