JUBU and other topics, a combo thread

Have you done 3rd cat delete yet?

I’m no expert, but it doesn’t seem like big power is coming from swapping catback on this car.

The damn exhaust manifolds are the problem.

But 3rd cat delete is easy money for sound and power.

Yea .. GRP delete. Absolutely money well spent. I’m definitely targeting the Aerie headers and will probably purchase right after I get my initial JUBU parts. Headers plus 3rd cat/exhaust on the Emira seems to be producing the F1 sound that you hear in the Valvetronic videos. Sounds ridiculously good. And since I run stock on valve controller, I wont annoy everyone on the road. Just F1 when I go WOT at high rpm. Those are my thoughts on that.

if I recall correctly, I think @Eagle7 thinks exhaust is holding back flow….

That said, exhaust is not at the top of my list.. may or may not upgrade.

EDIT: The JUBU header looks super nice but at $2400 insulated… thats before taxes, shipping, tariff… I had to look at alternatives like the Aerie piece.

How much of a power gain?

This ^
What you don't like oem camry/rav4 un-even length headers? LOL

Catless headers will be the most gain for the exhaust + 3rd cat delete. If you want to keep a cat for emissions or smell, any exhaust shop can weld in one of these near where the original 3rd cat was without being a restriction (#85032) https://www.gsportbygesi.com/g-sport-emissions-systems-products

Muffler options off the top of my head include valvetronic or Larini, but you won't see gains in power really, just a bit more exotic sound.

I'd personally pay the ~$600 premium with Greg over Aerie for headers + mid pipe, because if you do have an issue he will fix it.

Here are 2 videos of my set up. I still need to get a driving one inside the car for anyone interested. I have the JUBU headers and Y pipe and the high flow cat which goes at the 3rd cat area. I had the Milltek delete and with this set up I’m back to just 1 cat. I do have the Milltek exhaust so it’s not on the stock one. I absolutely love the sound. My values stays open 100% of the time no need to do OEM or close it. It’s gets F1 exotic sounding right at 5k and above.

Nothing dramatic but it’s $200 and it’s a guaranteed win on both sound and power. Also probably less heat soak

If this is the Ti exhaust, I recommend cancelling the order or atleast being aware of the risks. There's 4 or 5 known instances of the muffler area exploding (in the same location on every one) and the most recent one (2 weeks ago) nearly burnt down an Evora because of it.

source? I'm sure @Aerie would like to comment on this

it’s true, and aerie has revised the design since the failures, at least once (v2).

Idk if any v2 have failed.

I don’t have any personal experience w the part

Again, a source would be good. I've had both v1 and v2 and no explosions

Multiple photos have been posted. They’re already on here.

No one said they all explode!

That may be the case, not sure. I really like my aerie shifter. I’m just saying it’s clear there were some issues with more than one exhaust popping.
