Has any1 fitted a MSSK13 rear box the pipe diameter seems to big for the axle pipe I’ve got am I missing a reducer??

I had one fitted for a while. I had to get an adaptor pipe welded onto the axle pipe. The back box is 2,3/4 inch and the axle pipe is 2.5 inch.

But I found that it still didn't fit how I wanted so ended up changing it after a couple months.

I've still got the system so can take some pics if you need.

When i got my system i had to get a spacer for cat pipe to join to centre section.

If i remember right it was 55mm to 64mm so it slotted over standard system and into new system.

If you have the backbox why not buy the non resonated centre pipe to go with it

So your trying to fit the back box to the standard system? Indeed won't fit the standard system is 2.25 the miltek is 2.5, I'm selling a centre pipe non resonated and a reducer too all miltek, so you would only need the axle pipe from miltek and your have a complete cat back system

the box pipe is 2.75 (69.85mm) and axle pipe is 2.5 (63.5mm) both milltek . need reducer

being a 2 3/4 back box i take it u have the jet style tailpipe(twin round) best bet is to get in touch with miltec about a reducer as most people will have the 2 1/4 -2 1/2 that u get with the cat back setup
