i was due to fit my h&s centre section tonight supposed to be 2 and half inch but it tapers down to 2 inch where it meets the back box
on my nur spec back box and the h & s back box i have the piping is 3 inch and tapers down to 2 and half , surely its a big restriction ? im strongly thinking of returning it
any ideas ??
