I have the Pipes electric cutouts--and the lth, catted x pipe and GT500 axle backs--very loud, but NICE--Ithis is my seet up; LTH, than xpipe, than further back, (took out resenators) and the cutouts just ahead of rear tires,
I feel some loss of power at Hi rpms when the cutouts are open. I think we need back pressure or lose HP. So I plan on leaving them closed when on the strip, They sure change the sound tho!!
