Removing chrome tips - petrol

I would think that the inner ring is a support to stop the exhaust from being collapsed by over enthusiastic spanner use on the clamp bolt.
But from those photos I cannot see how the chrome tip is held.
Is it in fact just a push fit?

The chrome tip is welded to the middle ring (one spot at the top back which you can just about see at the 12 o'clock position and one spot at the front inside lip), as are the two parts of the clamp.

From the shape of the inner ring, I was thinking that it was to allow for better alignment of the exhaust tip.

I always spray Dr Magic/Oven Pride into them on my TDI, it foams up and drips out black. Leave it overnight and then hose them next time you clean the car - repeat 2-3 times. I do this annually before the MOT so they think the DPF has no 'issues' as the inside become completly clean silver metal again..

Hat tip to Snap dragon on the oven cleaner tip. I taped off the bumpers and gave a liberal spray of BBQ cleaner, outside and in. Left for about two hours and put newspaper underneath. I bought a bottle scrubber, took off the handle and used a drill to clean the inside of the tips with bucket of hot water to dip the brush in and clean as i went. Then i hit it with t-cut metal polish. Took me less than 10 mins per exhaust tip.

Compared to the hour or so I see detailers using tons of metal polish this was a super hack. The BBQ cleaner literally hoofed the carbon deposits off...

Nice one Snap...
