Mickthebus's Exhaust Pipe Question

[Mickthebus]

I have a 2003 1.8 club se saloon i have recently found out that the exhaust is one complete unit from front to back with no joints whatsoever.The car has only done 44000 mls so i presume its the original fitting. Has anyone experienced the same problem when time to replace a section. Any advice would be most welcome

The originals are indeed one piece .
It is common practice when replacing a back box to have to cut the old one off at the appropriate point , and the replacement will usually have a flared pipe to be clamped back on. Aftermarket products usually also come with their own hanger straps so the original brackets can be discarded .
Will you be doing it yourself or taking it to a garage ?

Done a couple with the original exhaust in place. A 1.8T which needed a sleeve as an adapter, and quite recently a 2.5, an 18 year old car still with the original exhaust. The 2.5 didn't need a sleeve, fitted a Walker exhaust as I like the strap which it comes with, fit the strap first and then slide the silencer into it - I like an easy life. In both cases I just used an angle grinder to cut the original pipework (and even the old rubber mounts, stinks but it's quick & easy).

All factory fitted systems were one piece, but the MGR replacements are in sections which are butt-joined using a compression sleeve. The majority of alternative, after-market spares will have a swaged end that slips over the original pipe and clamped with a U-bolt, but products may vary. You can see how the OEM parts are handled on the Xpart/Rimmer website: https://rimmerbros.com/ItemList--Rov...ystem--m-12894

Just a minor point. Unless it's a very specific fitment, to keep it cheap and simple aftermarket units have SPLIT ends that slip over the outside of the original tubes that have been cut (truncated).
Swaged ends are a dished/flared arrangement where one part is a female (concave), the other a male (convex) that are pulled into engagement using 'V' section, two-piece 'C' clamp (the 'V' acts as a wedge to pull the two pieces together to form a tight seal).
