just decellerate quickly, dump a load of fuel and mess up the cat.

Excessive popping can damage the cat in your exhaust. What it normally causes it is unburnt hydrocarbons on over run re-igniting in the exhaust

I just slow down from high speed in 4th gear and it pops nicely. As said above you dont want fast and furious style poping as it can damage the cat. When you see powerful cars blasting out flames its normally down to valve overlap, unless they have a flamer kit on :up:

Mine's just started doing this at around 1300miles. Are they noticeably loud? always seems louder when I slow down and go over speed bumps, makes me think something loose is rattling about under the car (could very well be for all i know)

just get a better exhaust if you want an audible quality to your exhaust. mine does it and i hate it. Nothing more embarassing than a car that sounds like its got a cold.

i have noticed that the 160 will pop alot more than a 105 with an x power oval exhaust...i have a 105 and it still gives a noticable pop when de-celerating matey

noticable? It sounds like something is rattling when I slow down for speed bumps / bumpy roads. I'm pretty sure there isn't but knowing my luck :p

If anyone would like de cats i can get them for any of the z's but be warned they make your car sound very very VERY!!!! raspy and you will also need to increase air flow at front end drastically to prvent losing back pressure in the exhaust, anyways ceramic de cat from £50 and manifold de cat £80 ( as there are two on most of the Z models a starter and the main. my advice is keep the main and sod the starter off, that way MOT peeps are happy and you get a little more torque.

There are two cats the starter and main. the starter is on the mainifold if you pop the bonnet you'll see it. the main is in the next section from the mainifold. in the early days 214 wedge type days Rovers had single point injection then they fitted cats and moved to multipoint to compensate for this, that should give an idea on how much of a restriction they are.
