R56 Exhaust toy

Recommended Posts

For some time I have wanted to change the exhaust on my SD but not many people make them, so I decided to do a bit of research and found out the back box is the same for the petrol as it is for the diesel.


Happy days......... you'd think


Mini (probably like most manufacturers) have decided to make there exhausts as one complete section front to back. This resulted in me not wanting to cut my original exhaust incase everything went south and it needed to go back on the car sharpish.


Fast Forward a few months I purchased a back box from @bornared and decided to chop to up

I decided to open the box to see what was inside and what could be removed ! I removed lots and lots of fibreglass rope that is used for sound deadening and then sealed the box back up again (with the help of Colin's welder). I do remember my welding being better than what it is now but when I think back it mush be 19years since I welded at work.


I purchased some cones and 3.5" slash cut pip and progressed to make some tips. Due to alignment issues the tips are only tacked on but paint a picture.

The only draw back is that I have found out the N14 and N18 have different pipework. The N14 bends sideways where as the N18 doesn't. No biggie, I can easy chop the bends out and weld the straights back together. Unless anyone fancies an asbo N18 exhaust lol ! The only part I need to fix is the length of the tips, I've made them the same length as my current tips so I need to take an inch out between the back box and the tip

Im interested in hearing it on a petrol as the diesels don't develop much more volume "apparently" and as mentioned will take a lot more work to get it to fit mine

I have no idea of volume as I have no experience of anyone doing this, possibly as loud as a decat with no other mods. I was intending to put it on mine where I’ve heard there is very little increase in volume even with a straight through.

If you can weld (my skills are questionable), it’s a piece of cake. Cut it open, pull out the fibreglass rope and weld it back up. As for the tips, I’ve realised there are things I should have done to make it more aesthetically pleasing.



Keep asking those questions Adam, I might not have answers but I can try

A little bit of an update,


I’ve shortened the pipes coming out the back box to reduce the overall length to match that of a diffuser.

I made a jig to hold both tips parallel and welded them on

The welding isn’t pretty but can be tidied up
