what links?
sorry, did not want my original post to be too long, so I just summarized my research

here are some links with a summary of each

note that it seems that I cannot post links to the "face" site nor to the "read it" site

https://www.civicxi.com/forum/threads/the-fl5-track-junkie-thread.52760/page-82
CCV catch can spiked crankcase pressure, leading to oil ejection from turbo seals on decel with visible smoke clouds. Recommends venting or larger lines to mitigate.

TheFace /groups/typerownersofficial/posts/10165335923225744/
Type R Owners group thread on PCV vs. CCV cans for FL5. Multiple users report exhaust smoke after Radium dual kit install, attributed to over-restriction on CCV side and shop confirmed it pushes oil to turbo/exhaust.

TheFace /groups/typerownersofficial/posts/10164685263880744/
Radium CCV catch can was deemed too restrictive, causing blow-by and positive crankcase pressure that forces oil past turbo seals into exhaust.

ReadIt /r/WRX/comments/170m8qp/radium_dual_catch_can_install_a_lot_smoke_at_idle/
WRX owner (similar turbo/PCV setup) describes heavy white/blue smoke at idle post-Radium dual install. Comments point to loose fittings or improper venting creating backpressure, fixed by rechecking hoses. this is similar to the FL5 symptoms.

ReadIt /r/wrx_vb/comments/15mrrrz/ccv_vs_pcv_catchcan/
Thread on CCV vs PCV cans. Warns that a restrictive CCV routing sends oil to turbo inlet, reducing efficiency and causing exhaust smoke from bearing contamination.

ReadIt /r/wrx_vb/comments/1bhvfct/evidence_catch_cansaoss_are_needed_on_these_cars/
Detailed WRX analysis showing oil from crankcase entering turbo via restricted paths, leading to intercooler fouling and blue exhaust smoke

ReadIt /r/wrx_vb/comments/1ob7tp9/2024_wrx_burning_1l_per_3500km_dealership_will_be/
2024 WRX owner burning oil post-mods installs Radium dual cans to address. Reports initial smoke reduction but notes ongoing monitoring for CCV pressure pushing residue to exhaust.

https://www.bimmerforums.com/forum/...-oil-after-Radium-Catch-can-PCV-valve-install
BMW M54 thread (turbo-adjacent blow-by issues) details big blue smoke puffs on throttle from idle after Radium PCV can install. The cause was restricted flow leading to oil pushing past seals. It was resolved by larger hoses and check valve tweaks.

https://www.supramkv.com/threads/address-blow-by-oil-ccv-or-pcv-catch-can.33616/
Supra MKV forum on CCV/PCV cans: Blocking/restricting CCV line caused immediate exhaust smoke from oil blow-by. Users recommend non-restrictive routing to avoid turbo bearing contamination. again similar to FL5.

FK8/FL5 Radium review. Notes oil vapors slip through if pressure builds. Emphases proper install, with tips on monitoring for exhaust residue.

Will the tune be a before and after just with the intake?
The plan is to perform some before and after testing, but the measurements won't be clean. I'll do what I can and share the results.

In the spirit of OEM+. I think I’ve finally gotten around to finish installing all the creature comforts I’ve been allocating. I’m sure the taste is not for everyone and many will say well why didn’t you just get a ITS(DE5). Well this has always been my dream car to own since a young age (EK9). Fast forward modern amenities. Love everything about it.

Love the door pulls @maxhazards how are they?
Top notch quality. I believe this was the first mod I did. Bought it from the IG user turbo11thcivic. There’s a newer version (See below) of these with a full CF inlay I’d call them v2. I like the v1 instead. But to each their own. Almost 9 months later still going strong.

Dropped my car off at the shop this morning to have the Spoon Rigid Collars and Front Stiff Plate installed. My alignment was a little off prior, cause it drives so much better now and feels smoother.
Did the rigid collars make any material impact on reducing the nvh and resonance on startup and low rpms from your rear motor mount? I’m looking for ways to reduce the resonance I hear at low rpms from my wunderladen rmm and curious if rigid collars helps with that. Thanks

I really did not have much NVH with the Wunderladen RMM to begin with, just at a cold start. The Rigid Collars barely helped reduce the NVH from a cold start, but I feel like they've helped the most with some road noise and vibrations I would have going over bumps and rough patches of road.

I also have the LTDL Performance Stabilizer Links from Two Step Performance as well, so that also is reducing what vibrations I may have. Its very much like the performance dampers from Mugen and Spoon.
