i have a 1997 1275i mini,ive just had part of the exhaust replaced due to the back box blowing.
the old box (the back one of the two) was qiute wide ,have just looked under and the new piece has two rather narrow boxes !
as you can tell im clueless really,so was just wanting confirmation this is correct ,and if not that its ok.

the rover standard mpi exhaust system (if it was intro'd in 1996) did indeed have a wider, non-cilindrical black coloured rear box, with the primary silencer being your usual cylinder shapped silver thing. When rover gave up the mini, these didn't make it through to the continued stock... you cannot for love or money find them new.

Mine came with a twin box peashooter which sounds like it's the same as yours, it's from cat back and appears to be what the garages use to replace exhaust systems on MPIs. The standard exhaust system on late models should have a chrome tip, this one doesn't. It could be the exhaust system they used on the SPi, as that has a cat as well.

If you do want to replace it with a proper standard MPi system, your best bet is a second hand one on Ebay.

This is a standard MPi exhaust...



This is the peashooter exhaust mine came with...

Yep I has the same problem for my 1999 mpi I found I couldn’t get a new back box .. that was three years ago now .. So I just fitted a standard replacement back box that fit's both spi & mpi, that we got from our local exhaust place


Mini_Magic that is the same peashooter i got got for my mpi lol

I think that only came with the Sportspack MPis, MM. Non Sportspacks came with the peashooter type, I fink.

If someone wants one of the chrome tail pipe trims for the standard sportspack exhaust, I have one sitting in my cellar looking for a home......

I believe that all MPi Minis came with those exhaust systems as there were no poverty spec MPi Minis, only the Cooper, Cooper Sport, Mini 40 etc.

As I said above, I think the peashooter exhaust is from the SPi models as garages are too cheap to order in a MPi exhaust when replacing an exhaust system.

the peashooter is whats listed for mpi's in the big pile of parts books i have at work. the other style is available, but nobody keeps them in stock and theyre not cheap.

cheers guys ! was a bit concerned it may not have been adequate and may affect or damage the performance, but seems to be commonplace.

I was under there recently and noticed that the rear box was rotting away from the outside. when I get some time I am going to fabricate a sheet metal cover to go over the existing one if it ever completely fails since I cant imagine how difficult it would be to acquire over here in the states.

bin the standard mild steel one, and fit a stainless steel one instead, looks nicer, lasts ages etc. go for something along the lines of an RC40 style if you want it to look standard and sound fairly quiet. will make a slight difference to the performance too.
