It's definitely deeper, but I haven't heard it from outside the car yet (if you know what I mean - so it's hard to tell!)

The OEM 1M axle back that Stu installed on his 135i (120d) has been modified.
It has had the baffles removed and the canister internals redirected.

I installed this unit on my 1M some time ago, hooked up to the N55 mids.

It was actually quieter than my OEM unmodified axle back.. I removed it after a couple of hours, so I can understand why Stu is not 100% happy with the exhaust tone.

The quad install and mod on the other hand is awesome and if I had a 135i, would do this in a heart beat as it looks awesome and OEM.

The 135i charcoal canister bolts up to the 1M battery box, but you do need to disassemble the pipes and fittings, relocate and shorten them then reassemble the pipe work to the canister and reinstall.

It all looks OEM when done.

Looks incredible - congrats!

If this was available in Melbourne I'd gladly give up my N55 135i and my wallet to have it done. If the exhaust note is as aggressive as the BMW 135i performance exhaust, I'd be all over it.

Looks awesome!!!!!!!

Nicely done. Great work stu + Pete + chris

[chrisN]

good shit stu!

i like the choice of outer quads rather than inner quads too. accentuates the cars width much better.

the other big thread on it and the people doing it WERE mostly in the US (LHD) and weren't sure if it was needed for RHD

did it need any of the 'fuel system' stuff? or just the tray/cables/mounting and other 'obvious' stuff?

Hey

The Evap canister itself is the same on the 1M and 135i. We needed 1M Evap canister hoses to connect to the relocated position of the canister.

The hoses are more like tubes which do not flex much and you risk cracking or pinching off the flow if you bend them.

Do you guys even have to have the Evap canister in Australia? I know a lot of regions do not.

Everyone should try to get slek or some small CF manufacturer to make a diffuser that can accommodate the 1m exhaust and bolt up to an MSport bumper.

I'm amazed... Nice work. But for the parts can you tell how much $$$ you have spent for parts?

[Rikx1M]

Sweet...thanks for having the gonads to do this mod...gives us all encouragement to do our own special things that may not make sense.

M135i 😃

I like this ... there's finally going to be a market for my used exhaust!

I doubt it - can't feel any difference

I think he means he prefers outer quads than inner... but then again who knows what pavo is on about

I'm sure there are places in Melb who could do this!!

Being in Europe I'm sure you could get the parts much cheaper, here it's a little over $1k AUD for the parts excluding the 1M exhaust and excluding labour.

If you can find a cheaper diffuser it'll be cheaper again.

I reckon this would look good too, yeh I know it's a truck AND its a Chrysler, but I like the big centre pipe look.

[PeteA]

There's another thread like this over in the main section of this forum:

Looks pretty similar setup to yours Stu. It goes into some detail about battery leads and steam pipes as well.

THAT could be interesting... maybe when I get bored of this look!

But why 2, when you could get 3!!!



Regardless, whether 2 or 3, you would need someone to fabricate some kind of custom rear diffuser and I don't think they make centre exhaust diffusers yet.

Nice work!

Only two little pipes for that big 8...

Must be the sepo's attempt at fuel efficiency...

" if it can't get out... Means less needs to go in"...

[flinchy]

any chance you (or someone) could post a pic of the drivers side underneath battery tray bit? just want to see what's attached to it on that side (the non exhaust pipe side)

[1SER135]

Ill have mine on by Friday. Mine is going to have Hartge diffuser and the two outside tips with be unmuffled ALA Akrapovic 1M exhaust. Will post a sounds clip as well if I get the chance
