prodrive p1 upgrade rear box
#3
I have an original P1 backbox on my MY99 Turbo, and it has certainly improved the look and noise at tickover. What difference would this backbox make to noise & performance? Presumably it is freer flowing than the standard one.
Any pics available? If so, e-mail me, as I am interested.
