This has been talked about
here around a year ago, but I'm not sure it came up with any conclusive answers.
I bought the TRD exhaust used without the original hardware, so improvised during installation. The gasket from cat-to-midpipe I replaced just fine, but there's a specific one from the midpipe to the muffler I didn't have. I never put that on so just lived with exhaust leak until I noticed it start to rattle, and now I'm trying to get a hold of the original hardware kit to install.
This would be the kit I'm referring to, but cannot - for the LIFE of me - find anywhere to buy it. I tried my dealership and the parts department were no help. Does anyone happen to know if/where I can find this set online anywhere?
Also, it looks like
suprastore has them, but I'm not sure how reliable they are.
UPDATE: I went to Amazon and purchased a 2.5" donut gasket in the hopes that this will fit.
Subsequently, my dealership called me back about the part and it turns out the reason why he could not find it in the system is because it was physically removed (or some other bullshit). Long story short, "HQ" re-added it to his system and he will be able to order it, as long as I get there before the dealership closes. Since I've got the cash, I'll probably go in and order... but when the part from Amazon arrives, I'll likely install that first before I can replace.
The part number is PTR03-18131-AA, which is identical to the actual exhaust system's part number, except for the last two digits, "-AA," which is the indicator that it is the hardware.
UPDATE 2: Picked up the hardware kit from the dealership... I would've installed them, but it's raining. I'll post pictures below of the kit since it seems no other image exists besides the stock TRDusa one.
