S1 exhaust and Pipercross induction

My exige (when i pick it up) will have the s1 exhaust and pipercross induction system… would appreciate any comments from other owners who have 1 or both of these as to the effects they have on the car

See my thread with the clip of my Exige with Stage 2

Stage 1 is a bit too quiet for me but should at least get you on most tracks.
