Evora 400 decat pipe - WOW!

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.

Hi Guys,
Sorry for the longer than expected wait time on these.
The fab shop we use isnt big by any means and they got a bit overloaded with a job for Tesla.
Everyone's Decat is headed out the door today though!

We were very pleased with the finish/weld quality on these when we picked them up.

Agree with the product being very nicely done!

Let me know how your installs go, please. The straight cut end was a little flared on mine and won't slip into the OE exhaust so I'm going to have to slowly circumferentially tap it with a hammer it to neck it down to size. FYI OE cat weighed 5.99lbs, decat pipe weighs just less than 3lbs on my scale.

I installed my GRP decat yesterday. It wasn’t bad. I used a screwdriver to open the pipe on the muffler side. I took the muffler off (4 hanger screws), enlarged the opening, and used a rubber mallet to coerce the new pipe into place.
The difference in sound is immediately noticeable. It definitely has a more raw sound to it. I can’t wait to get it out on the road!

When I went to check exhaust clamp bolts (after they were heated up by letting the engine run and then let cool), I somehow managed to snap off the bolt on the V-band clamp on the engine side (not the muffler side). I was using my small 1/4" ratchet and it didn't take much effort to break so be careful.

Does anyone have a part number and/or how to get a new V-band clamp please? I tried an off-the shelf 3" stainless one from local auto parts store and it's too big across, even when cranked down.
