I am going to have a go at this over the next few days (off mid-week from work). Aiming for this look - appears to be the best fit I have seen so far. The pics are taken from a m135 rather than a m140..ImageImage

By way of update, I am happy with the end results. I took about 10mm from the tips and fine tuned the fit with a file. The result is close to the pics above and in my opinion, looks more subtle than what I had before.Image

Looks spot on, I think I'll shorten mine to as it's still in "wheel barrow" mode....Going to make some carbon fibre shrouds too as I've only got the chrome tips ATM.

Looks spot on! Did you find a way to cut them in situ or did you remove it all?

Basic question but what does the MPE do over standard? Does it just flow better? Does the standard have flaps where as MPE does not? Lastly when are the flaps open on the standard system?

The standard backbox (top) has perforations in different chambers to the MPE. That's why the MPE sounds a bit deeper and pops and bangs more.

That's a great photo! So where are the valves?

Great photo. The valve is top right in the standard. Just out of shot. Pretty pathetic that costs £700!!

So is the valve removed with MPE altogether?

Yes, I think you get a "dummy" socket to plug the original cable back in.

So, is the valve only on one pipe and doesn't affect the other?

Yes, no valve on 140 mpe.

So an aftermarket back box replacement will do a similar job and by pass the valve?

When is the valve open as standard?

This looks much better IMO. I have been holding back on the MPE so far as I really don't like the 'wheelbarrow' look.

I'll be fitting the MPE myself when it comes to it, so glad I can fettle with the tips to make it much more subtle. I will probably just stick with chrome tips too, not sure if that makes it any easier. I was contemplating to see if I could use the existing tips from the stock exhaust - does anyone know if that would be possible?

Yes, there a few to choose from. Other Exhaust will vary in sound though. But it's all subjective. Do a bit of research and go for the sound/price you prefer.

Mine was closed on startup. Open when sport is selected or WOT.
