I feel like a ticket magnet already... not sure I want the extra attention this might bring...
Is there any drone on the highway ?US Evora 400 owners, if you have not gotten the decat pipe (A132S0230F) that removes the unnecessary secondary cat that comes on US/Federal cars, you are doing yourself a huge disservice.
Just had mine installed today, and it COMPLETELY changes the exhaust note in a massively good way. The majority of Evora 400 reviews on YouTube talk about how amazing the exhaust sounds, but when I got mine I was pretty disappointed relative to my Evora S with Larini decat and exhaust, which I loved. Most of the reviews were on ROW cars which come from the factory without the secondary cat, while US/Federal cars have the secondary cat.
The 400 with the decat pipe makes the car sound like it should. It's loud, but not loud just for the sake of being obnoxiously loud (a la Jaguar F-Type). It's hard to believe that a Camry engine can sound this good. I could drive around for hours with the windows open just enjoying the exhaust note. It really is that good.
Good Info. Was on hte verge of doing the same thing as well. I wanted to keep the sport exhaust button functional but might spring for the plack exhaust instead. Love the SportsCarWorld people ive met there. Nice PeepsSo we didnt purchase the OEM part posted by OP, rather we just cut out the cat and installed a straight pipe.
Sound improvement is noticeable but modest. It is slightly louder, particularly under WOT, however not significantly so. Happy I did it, however, it did not produce a significantly different exhaust note.
Well, I'm in CA, and haven't had a 3rd cat since I bought the car. I've passed 2 smog tests so far, with values nowhere close to the limits. The great thing is most shops have zero clue as to how many cats the car is supposed to have, so it passes visual and emissions based on the 2 primaries. Of course YMMV depending on your state's smog laws, testing procedures, etc etc.Julian's comment begs the question: how much negative effect does removing the third cat cause vis a vis emissions compared to retaining it? Probably a hard one to answer.
