Could they go after the axle in place of the OPF filters? There are mounting brackets and shielding there already. That would shift some of the heat away from the engine too.
Of course, beautiful pipes.

FWIW...BMW has had many issues with their MPE (Ti performance exhaust) cracking...it's all over the bimmer forums. It is postulated (albeit unproven) to be a flaw in design rather than the materials used...point being I wouldn't jump to the conclusion that ALL Ti exhausts will crack simply because they are Ti. Ultimately, if a company gives a lifetime warranty against manufacturing failure/defects, then that should be good for most...provided making a claim under said warranty isn't a monumental PITA.

The M3/4s had 2 versions of the MPE. The first one had the problem with cracking, but to my knowledge there wasn't an issue with the V2. Also, they make MPE for other cars that I don't believe had any issues. As stated above I'm guessing it's due to design rather than materials used.

Things take time..
We’re currently building and finalising our non valved race pipes which will be available in silenced and non silenced form.
Two versions of Race manifolds
Three versions of OPF deletes
To add to our two versions of valved rear silencer replacement and two options of tips
There is no ‘one solution’ as you have found. You’re unsatisfied with the level of sound with your rear silenced replacement where as many many customers of ours already are absolutely over the moon with it and wouldn’t wish for anything more.
Same goes for our 991 GT model offerings, over 1000 customers running one of almost 40 different exhaust configurations we offer from a simple and subtle centre silencer replacement to a full manifold replacement with a non silenced race pipe. A 120dB flame throwing insane collection of parts.
This is why from the start we have and will continue to offer the largest and most comprehensive range of products to allow owners, with our guidance, to select the best possible solution for them.

i went to an audio acustics shop who already worked using sound deading to some exotic cars especially with GT3s, he just suggested to deadn the engine upper cover metal and its sorroundings a first phase using just hushmat and my finding for my GT4 718 were:
- the drone with oem exhaust from 2-2.5k is almost gone from noticiable - hardly noticeable
- the click sounds from the engine bay is hardly there when i was idling between traffic lights
- this is surely agreat suggested mod for those whos doing any exhaust setups for our GT and for those who’s paranoid from any drone in it.
my other take as i did this already it made the car quiter (near same when it had quite mode) but the positive it made the crappy bose system to be from bad - normal/acceptable
also done a must have mod relocating the annoyed passengers leg fire extinguisher and man it made a worthy change.

Relocated the fire extinguisher with just strong velcro it its a 100% perfect

It might be annoying to your passengers, but I'm pretty sure there is a valid reason it is located in the passenger foot well. Just sayin'

I expect he has too much free time on his hands if he’s still concerning himself with what we’re getting up to. Must be nice

Interesting reply Jonny, my comment was one of concern not confirmation, I would have thought that your reply would be to dispel such thoughts, not push someone away who reached out to you about purchasing one of your GPF sets.

My point is that inevitably those who feel threatened by our growing audience and reputation will no doubt continue to throw out such comments in order to attempt to disrupt our progress. Thankfully most can see through it so there’s really no need to address nor respond to their comments.
