Toyota Part Number: PTR03-89200
It comes stock on 2020 and 2021 TRD Pro 4Runner. I tried it on my 4th gen 2009 V6 4Runner and it fits perfectly. So I assume it will fit all V6 4th gen and 5th gen.
I got it new and it's been on my runner for less than a week w/ less than 200 mile of use. But Wifey doesn't like the sound, so I am putting it up for sale.
My own thread about this:
5th Gen Exhaust on 4th Gen?
MSRP: $775
I would like to avoid shipping if possible, it's heavy and bulky. But if you are willing to pay for shipping, it can be arranged. I still have all the packing material. But bear in mind, when I was looking around, some online dealers would charge $200-300 for shipping.
For those who live near Minneapolis, if you have less than a year old 4runner and would like to do a swap, a deal can be arranged.
The part pictures were taken before the install comparing with my old exhaust. It is still on my 4Runner. Picture of it installed is also attached.
