Whole lotta nothing for the Passport.

The intakes by AEM and HPS may fit as they make intakes for the Ridgeline and/or Pilot.

I went ahead and pulled the trigger on an HPS intake to see if it'll fit. It should be arriving soon (next day or two).

Exhausts, I found nothing. I even looked under to see if the system is multiple parts: headers/downpipe to the axle and then axle to the rear. As far as I can tell it's one long system from the headers/downpipe back to the rear. I do wonder if an Accord V6 exhaust would work. *shrug*

I could be wrong but I don't anticipate there being a high demand for an exhaust system for the HP so we may be stuck with cutting up the OEM system and adding, for example, a Magnaflow muffler.

Well, received the HPS intake and the instructions. They do not have them online, at least I couldn't find them. Interesting that you must completely remove the OEM breather and coolant hard line for the install.

I'm a computer noob but was able to get this picture from their instructions (created PDF).

AEM doesn't require this for their intake.

So I'm not sure about the HPS at this time.

I can confirm the AEM cold air intake made for Ridgelines/Pilots fits Passports perfectly. I had one on the ridgeline I traded for my Passport and swapped it over easily. Definitely feel it in the butt dyno, vtec sounds awesome, and the intake sounds even cooler on the passport due to the sportier oem exhaust. Gives it a nice growl at low rpms.

Thank you for posting this. I may end up returning the HPS and getting an AEM due to what seems to be a simpler install -- you don't have to remove coolant pipes. Admittedly I have not really looked under the door to really assess what I'm up against. Hopefully later today/evening.

And to be perfectly clear from my view due to this conversation getting a bid sideways: I do not purchase intakes or exhausts for performance gains. I purchase these parts for the sound enhancements. Besides, it's my money that I have earned, so I'll spend it on whatever I want to.

how does adding one of these affect the Honda warranty?

https://www.autoanything.com/popups/MossWarranty.aspx

"When accessorizing your vehicle with aftermarket parts, your warranty claim cannot be automatically denied, nor can your warranty be voided, if you install non-OEM parts in your vehicle. The burden is on the dealer to prove the aftermarket parts caused the failure. For example, if your windshield wiper motors fail, your vehicle’s warranty claim can’t be denied because you installed aftermarket windshield wipers that are different from OEM (Original Equipment Manufacturer) parts. Similarly, if a wheel bearing fails or a fan belt snaps and you have an aftermarket exhaust installed, the dealership would have to prove the exhaust system caused the bearing failure or the belt to snap in order to deny a warranty claim. In these types of scenarios, the dealership should have no reason to deny your claims."

Ah, the hell with it. Gonna return the HPS and get an AEM based upon swenpaylay's fitment test.

Sorry for those who wanted me to be the test rig for the HPS but knowing I have to remove OEM plumbing (coolant hard line) sent me running for the hills.

Honda Pilot video... to get an idea.

My AEM intake arrived today. Wow, the filter is bigger than what comes with the HPS intake. Hoping for an install this weekend.

Installed the AEM today.

Can you post some picture or maybe a YouTube clip of how it sounds?? please ?

I reached out to Magnaflow and Borla via email and asked if they plan to develop and release an exhaust system for the HP. Will post if/when I hear back from either.

Borla's response:

We do not currently have plans to develop on that platform, but we are always watching the market and adjusting accordingly. We may choose to do one in the future. Stay tuned. Thank you for your patience.

 

[david16]

^ not there yet bro.... waiting it out right now to see what may become available.

Magnaflow's response:

At this time it does not look like we have anything in production for your vehicle. Magnaflow designs exhausts for vehicles based on demand and the amount of customer requests we receive. I will provide a link below to our development program for a chance to have a system designed using your vehicle.

Idk if this has already been discussed, but im thinking about removing the resonators marked at numbers 12 and 13..... Straight pipe at those points should add enough "character" to the exhaust without over doing it.... Has anyone done this? Thoughts?

EDIT: I noticed this exact topic was done on another thread.... but has this been done yet?

I was thinking about it but haven't done it; jonii makes a good recommendation: just remove them and see if there's any sound difference. May give that a go one of these days...

 

[david16]

Thanks for handling this experiment. I was about to crawl under there this weekend and have a go of it. You saved me some time.

Looks like a trip at some point to a muffler shop and have them fabricate a modified part #11 in the above diagram.

 

[david16]

I'm thinking one is a resonator and the other is the actual muffler. My guess is the first one (closest to the engine) is the resonator but that's a guess.
