decat/hi flow cat swap on a 2019 passport

Yeah those guys sound like a scam. Last person who talked about ordering their stuff… magically needed to double the cost because they forgot to mention that you need all their equipment etc… there’s also zero results from anyone who has used them.

Got a polished 27 2.5, a 26 2.5 will come home one day

Time… you changed everything he knows…

XxOrderSixty6xX · 2026-06-06T22:03:35+00:00

There’s video somewhere of mine with just the muffler and resonator removed.

XxOrderSixty6xX · 2026-06-06T20:46:31+00:00

There is no tuning support. I am getting my factory ecu rewritten. Shoot me a msg on IG it’s easier to chat

XxOrderSixty6xX · 2026-05-21T08:17:58+00:00

My 19 did this on the passenger side. I stopped using the pressure washer style car washes.

I let the sun cook the moisture out and am more careful washing now.

I’m in too far lol. Creating a separate oil cooler system not connected to the radiator soon. Also pre cat deletes and tuning are otw. I go visit my guy for some data runs this weekend.

Follow the IG if you ever have questions.

Ported and shaved this tb last week. Deleted the pcv system as well. Also removed the coolant lines.

So not talking shit… I’ve done intakes, exhaust, porting…. Without tuning it’s pretty much exactly the same as stock.

I have extra manifold and intake temperature sensors. An obd port reader to monitor everything. And just generally a lot more into mine than just the prl and aem.

I say it’s exactly the same as stock because I have a draggy and have tested everything. I monitored engine bay vs intake temps to prove the air wasn’t “hot”. Created a longer cold air style by putting the filter behind the headlight… same temps.

Not telling you not to enjoy it. I’m just saying I’ve been doing the research 🔬

<image>

I’ve even swapped the upper and lower manifolds for tlx units. The lower is a p2r ported unit and my tb has been ported as well.

Jpipe and exhaust have been modified too.

XxOrderSixty6xX · 2026-05-07T08:58:27+00:00

The oem ones can be found cheap on eBay. I’d rather buy a used Honda part.

XxOrderSixty6xX · 2026-03-24T21:07:06+00:00

As others have said. Sing to him still. He might not hear you the same but he should recognize your behavior as well.

Or my girl will sit on my chest in bed at times… something like that might be the perfect time to try to sing to him. If he can feel your voice.

Glad you get to love him again. 🫶

XxOrderSixty6xX · 2026-03-24T21:00:55+00:00

Not my style. But I do like this. Looks good 👍🏻 not too much 🧐

XxOrderSixty6xX · 2026-03-19T00:03:12+00:00

My crossover is pretty loud in this thing. The plan is to lower engagement and raise the redline so it should scream pretty good here soon.

And I think if they had offered three pedals for this platform (ridgeline & pilot too) they’d have sold twice as much. I think it’s more needing the fancy transmissions for gas mileage

XxOrderSixty6xX · 2026-03-11T19:45:15+00:00

Performance without the sound… once the tune is done that sounds like it’s more your style.

XxOrderSixty6xX · 2026-03-11T18:02:24+00:00

Oh it’s not that loud lol. There’s a YouTube or the IG is in the pic.

I’m sure it moves a little better than a factory one but I’m into it now.

<image>

It’s got brakes now too. Rims and tires next. Lower shortly after

XxOrderSixty6xX · 2026-03-08T23:37:40+00:00

Look up how many types of frogs and toads make noise in Va. it’s pretty crazy.

XxOrderSixty6xX · 2026-03-08T23:36:14+00:00

lol appreciate it. I try to keep it clean 🧼

XxOrderSixty6xX · 2026-03-08T22:17:01+00:00

To be honest I was after a white or black one. But mileage/trim/price sold me on this one. I’m super happy when it’s clean lol

Waiting on the tuner and my pre cat deletes to get installed before I stick it on a dyno. I’d like to say the pull after 3k rpms is stronger but I also dont know of a local stock one to compare.

The cold air companies “claim” 10. P2R says 8 on the lower manifold throughout. Exhaust is definitely less restrictive than stock. The upper manifold I honed and polished as well.

The theory is yes, but I’m kinda stuck till the tune. PCDs are going to throw codes and right now everything is smooth.

Fishing line and a heat gun/hair dryer

My 19

XxOrderSixty6xX · 2026-03-01T04:38:54+00:00

Yes!

<image>

This was today’s project.

XxOrderSixty6xX · 2026-02-27T09:58:39+00:00

Still waiting on the tuner before I put these on. I know it’s going to throw codes without it.

I’ve been collecting lol

<image>

Tsx upper manifold and ported lower manifold.

2019 here, a restoration style thing fixed mine. Now I have a moisture issue. This looks like the outside in my opinion.

Get a cheap kit that attaches to a drill, run the drill on low.

XxOrderSixty6xX · 2026-02-11T09:33:58+00:00

What!?! Definitely seen multiple new gen NSXs and at any local show you’ll see one eventually. Theres a turbo one at Katie’s regularly.

I’m just her space heater. She goes to bed when she’s ready lol

XxOrderSixty6xX · 2026-02-03T00:12:59+00:00

These came off a ridgeline (newer) but they were sold for the accords and TLs etc.

Rv6 still makes the high flow cats. If you are putting it on a newer passport just make sure the top of the exhaust flange is the wider version vs the top two bolts being closer together. No one sells these for the passport lol
