Tail pipe tip for TRD pro 2025?

[j41ruX]

I’m looking to purchase a tail pipe tip for my 2025 hybrid TRD pro, I measured the exhaust pipe and it was 2.75 inches, but I’m not sure if I must purchase the 3 inches one and adjust it? or what it’s recommended?

Thanks for your input as always!

If you drive with the rear tailgate window down on your 4Runner be aware that changing the airflow dynamics (extending the tail pipe) could possibly cause exhaust fumes to enter the cabin through the back tailgate window. Just something to think about.

it's virtually the same with or without an extension
(a) is w/o diffuser

Please forgive my ignorance (it has been 40 years since I studied fluid dynamics)

Does either of those images represent a 4R with rear window open? And how does what appears to be two different vehicles make it a good comparison?

it is a generic SUV airflow profile not 4runner open window specific.

If you had asked me ahead of time I would have suited your needs, but you didn't
so I didn't

if you install the oem accessory exhaust tip correctly, the original oem exhaust tip will butt right up against the inner curl of the black out chrome tip.

so you only technically extend the tip about maybe 1/4 or 1/2 inch

but where you install it is totally up to you. some like to extend the tip out further to get a more rugged look or vary it.

but normally you install it until the you cant slide it any further onto the original exhaust tip.

Like that but black mate, could you please share the specs and dimensions?

Thanks !

It is a very tight fit on the Pro. It does fit perfect though!

As far as the back window, the manual clearly states that you should never drive with the back window open because of the possibility of fumes entering the vehicle. I believe that is true for all vehicles. That said, this may be more of a lawyer-required clause than truth, although it does make sense to me. Plenty of other windows to open while driving.

on my 5th gen i ran the window down all the time when i could.

i did 1/4, 1/2 and full down at 75 mph or around town between 30-45 mph.

the fumes really didnt get annoying for me at least (i am not sensitive to the fumes). the biggest issue is the amount of dust/dirt/grime you suck in via the back window. it will vary depending on if you have any other windows open with the back window. if you have any window open/cracked you will suck in more since you are creating a flow path from the back to the front, otherwise, you have a dead head space of air if you only open the roll down window (this is my observation, not technical in anyway)

after 12 yrs of doing this, the headliner, interior is coated in dirt/grime/dust. this was the last time i was going to be able to actually enjoy the back window down as much as i wanted to (and yes i traded my 2014 in without cleaning any part of it, and they still gave my 19k in trade in on 120k mileage vehicle, but then again, only 1 seat was ever used and i kept the back seats folded 99% of the time, so most of the vehicle was never touched)

on my 2025 4R, i will never roll down the window as this suppose to be my retirement vehicle.

so take that as you will

As much as I would like the air flow, I do not want the toxic fumes...little to do with the smell. I can get plenty of air with all the other windows. That said, at freeway speeds especially I usually have them all shut with climate control on, as that is quieter and more efficient. Off road could be different depending on the temperature.
