I went with the JBA shorties. Install with new cats, a custom built Y-pipe and rear cat delete was just north of 1K. Any good shop will be able to build you a Y-pipe cheaper than buying aftermarket. It will definitely clear your CEL if its just P0420 & 430.. I went back a year later and had them...
No CEL. Shorties retain the main cats. I had them cutout the secondary ones which are not even really cats. The secondary sensors are upstream from those so no lights going on just over 4 years now.
I would assume you would have to pull the motor or drop the trans.
There is some info for 3rd gens but didn't see much else. Probably means it's not a common issue on 4th gens
Are you leaking or what's the reason for replacement?
I have the high flow AEM filter, JBA shorties with a custom Y pipe and Borla turbo style exhaust. It definitely has a little more pep but really only could tell at WOT. So unless you drive it like a racecar it's negligible aside from noise in most cases.
To get the most out of any of those mods...
Yeah that is odd. Not sure why there would be a difference but the PN I confirmed with my local dealer for an 08 V6 is the -35112.. So I guess that's in line with what I was able to find.
My 08 has 209k on it and mine is starting to show signs of failure.
Another members thread described similar issues with 230k.
Not an exact number but many other seem to be north of 180k when they do a replacement.
PN for the 4th gen is 7702035112
Sounds like your pump/sender unit is on its way out. I believe there is a sock/filter on the assembly in the tank. I have had similar issues with my 08 recently @ 209k.
It's hesitated & puked on me twice now. First was on an overpass incline with an almost empty tank (no light though). Second...
Those are just amber mini "marker" bulbs that come on with you headlights.
Should be Toyota PN 90981-15012
Otherwise a standard amber #2827 from a local box store
