Just a quick one guys,

currently got a blitz nur spec on my p1, fully decatted running 401bhp

looking at changing my exhaust for a h&s jap style, which i know will be too loud for track use,

but wondering if i have a normal style h&s backbox as well with the intention of using it on track, will that also be too loud?

im guessing the centre sections are the same, and to swap them id just have to change the backboxes?

anyone shed any light for me?


cheers
