I Stepped Up AGAIN (991.2 Turbo S)

Okay, so I posted this on another thread a few days ago, but realized I need to update this thread.
Had a pressure spike due to a WOT in manual mode but forgot I was in manual mode and when it didn't shift automatically, I let off at the rev limiter.
It spiked the boost and I heard a loud "POP". Thank God I was only 2 miles From the house. It drove fine home but with no boost.
I thought I only popped a hose or something. Turns out the Factory Y-pipe SUCKS and will split at the seems. Have a look
Long story short, I've been in a very tough and stressful Emergency Vehicle Driver Instructor class the last two weeks and haven't had time to do anything with it.
I did graduate the class thank Goodness, even though they have a 60% failure rate of this class. We started with 19 people and only graduated 9 people.
Now, I'm trying to decide to just go back to the factory Y-pipe (which I have one enroute, thanks to Sam by Design!! ), or to upgrade to aftermarket (IPD, do88, etc)
If I do upgrade, What brands to use and how far to upgrade??? do88 has the "Big Pack" that'll upgrade my IC's, hoses, and Y-pipe, but no Plenum.
Anybody have recommendation on what I should do and which brands to use? If so, where to get the best deals on said parts?? do88 IC's vs. like CSF IC's or others???
I'd rather have a kit that comes with new shrouds so as not to have to modify / cut my factor shrouds.
Here are the pics of the split factory Y-pipe..

Congratz on graduating the drivers course - bet you wished you had your TTS (without split y-pipe!) on some of the challenges 😎

Without a Doubt!!!! lol
I did get permission to drive down and take some laps on the Big Track though. Will kinda be link having a free track to test on when I want. Only 1.5 hrs. away.
Will just have to be careful. Decent run off but don't want to chance anything crazy.

I want to add by the way. To get my car to the shop or a buddies house (lot more room and tools) if I decide to do an upgrade / plugs / & air filter myself, I was able to JB Weld the blown cap back on the car.
Unfortunately, it as tight in there and I wasn't able to get it completely sealed. I just took the car for a ride. It was able to hold 10 psi of boost (Not going to push it further) and ran just fine, however I could hear a slight "Hiss" back there, so I know I do not have a perfect seal. I just wanted to close it off to be able to move the car without towing it somewhere.
Once I get the Y-pipe and / or upgraded parts (along with plugs and filter), I'll drive It over to my buddies and we'll knock it all out.
I'll post the short vid I shot of the JB Weld job. Have to upload it real quick.

As good a bush fix as I have ever seen; I hope it holds together...

That is just completely bizarre! I don’t think I’ve ever read about anyone’s Y-pipe splitting open like that! On the other hand, I would use this as an opportunity to upgrade to some aftermarket parts. From what I can tell, the Y-pipe and Plenum upgrades seem to have mixed feedback on whether they do or do not improve performance. But, I’m planning on doing these upgrades anyway. The DO88 Big pack seems like a great bargain, and you can get their plenum too when it’s back in stock.
As for which is better: DO88 or IPD? The times I have asked this question, the feedback I get is they are about the same although the DO88 products are less expensive. It’s hard to argue with lower price and similar performance, however, I am easily tricked. Sam and several others seem to swear by IPD products so I might yield to what appears to be more effective marketing and spend extra money on the IPD parts myself. Again, I’m the guy distracted by shiny objects so you may want to ignore this post.

Even the intakes can be susceptible to breakage.
Not saying it is expected but can be a possibility.

Just my luck to have something happen weird and not normal. lol
Yes, I think at a minimum, I'll eventually do a metal Y-pipe of some brand. do88 stuff does seem nice, but then again IPD does as well.
Sam seems to like both brands. He deals in either brand I think.
I too am like you when it comes to "shiny" things and being swayed easily. Hence me trying to take my time and make a good educated decision before going forward.
Only problem is, I can't really enjoy my car until l decide one path (Just replace with stock Y-pipe) or Aftermarket stuff / full kit (I'll need to order and receive parts before I can move forward with repairs).

Well look what I found. Seems my stock y-pipe failure isn't so uncommon.

Hasn't anyone done a DIY thread on the 991 Turbo / Turbo S??? I thought I saw one one time but can't seem to find it. Only the reg. 991.
We dug into mine today and we can not believe how tight it is to get the coil / plug out on the drivers side Rear most hole! This was after we figured out that the IC's had to be removed also.
Anybody have a clue how you get it out of there?? Remove the Turbo? Exhaust? or just the turbo heat shield?? Will it move past at that point??
That turbo hanger is the main thing in the way.
Any other info that'll help us would greatly be appreciated.

Also found out that the original / previous owner replaced the stock air filter with a BMC filter and also had Porsche of Houston install Champion FORGE Diverter Valves. Nice to know I have a couple extra mods for free.
Fixing my Y-pipe issue while it's apart also.

How are you going to fix your Y-pipe? Replacement/upgrade?
