M Performance exhaust replacement

[TyronF82]

Hi all,

Im looking for advice on the best way forward for my M Performance titanium exhaust on my M4 F82. The baffle plates in the muffler is loose and is causing a rattling sound. What's the best way to get around this? If I go stainless steel replacement, what can I do with my existing exhaust?

Thanks.

Find a place that is competent that can work with Titanium.

Cut the top part of the box that will not be visible, remove the broken guts, replace the internals and weld up.

100% - backbox mod it bro...much cheaper and still enjoy it.
Alister at XFlow did mine...EPIC!

Thank you, I've done this ~4 months ago, but I was advised it will not last - which it didn't. I don't want to repeat this exercise again. I have been informed that when titanium cracks, the fix becomes the weak spot.

It also involves the process on how it was welded , Ti really needs to be properly back purged, if we are being honest, there are not many welders that do this, hence the weld will always be compromised.

Agreed. Im in the Western Cape and there doesn't seem to be any welders who can do a proper job. Any other alternatives? I've been advised to replace it completely with stainless steel.

That is true, Mine lasted vover 5 years.
Alister does these to the M4s as well, give him a call Tyrone even for him just to check if he can help you out for now. Maybe worth a shot before fitting a full system, which he can also do but always good to have options bro.

Supreme Technik advised I go equal length stainless steel

Sounds the absolute best but it's a steep price to pay.

Before you did the repair, is this not a part that should've been warranted by BMW?
