Thought I'd post up my experience with these, and some adjustments I made - may help others struggling to clamp up the rear boxes tightly. - I have only had to do one side at this stage.
I guess most on here will have these given the mild steel OE flanges will have turned to dust by now. I had these fitted a couple of years ago.
The rear tailpipe alignment/position within the rear bumper aperture is adjusted here, so you need a solid fitting. I used a trolley jack under the exhaust to push it so it was touching the bumper and tightened up. When the jack is removed the exhaust sags giving about a 10-15mm gap.
I hit a snag though on the drivers rear box, I couldn't tighten the bolts enough to lock it onto the middle section - the bolts bottomed out. The result was the exhaust sagged on that side, and probably would have leaked, although I never tested it.
I was starting to worry that maybe I had damaged the flared ends of the exhaust where they join with the donut/gasket ring.
With nothing to lose I decided to machine down the clamps, so that they would be clamping on a smaller diameter area of the chamfer, hence tighter. I am pleased to say it worked a treat, and everything is rock solid and positioned nicely in the rear bumper.
I reduced the height by 1mm by sanding down all 4 of the pieces of the clamp - before and after
A bit of a bodge, but I carefully sanded using an angle grinder and coarse sand paper disc, holding the clamp piece flat onto the disc, measuring with a micrometer as I went to check the reduction was even across the clamp. Ideally a bench sander/grinder would have made the job easier.
Final check on alignment will be done once the wheels are back on, and off axle stands.
