3rd Cat Delete

[AndyVX]

CS is outsourced and knows nothing except what's on their scripted response sheets. An OEM sports/titanium exhaust will be available at some point.

How good is your info on that?

I mean, anything can change, but I'd say as good as it gets. I've been told they are working on OEM upgraded parts (including exhaust) through the LAP division directly from workers. I've seen carbon molds for Emira parts as well.

 

[AndyVX]

Good enough for me

Starting to think about upgrades, as I think the car isn't far away. I'm deciding between two 3rd cat deletes, the Milltek one and the the one from inokinetic. Anyone have any preferences or are they going to have very little between them?

Milltek Cat Bypass Pipe for Emira

Features: Transforms performance and drive-ability Sharper throttle response Substantial weight saving over original equipment systems Precision, quality controlled manufacture Highest quality aircraft grade stainless steel Low pressure systems for maximum performance Responsibly developed and...

Emira deCAT — InoKinetic

The Most Amazing Sound for the Money! The addition of this simple, cost-effective pipe will transform your Emira into an awesome sounding sportscar that will rival almost any Italian exotic. It is really an ideal sonic upgrade that does NOT add any drone yet allows the car to wail like it should! B

I don’t think there is much science behind this part. It’s just a tube and the sound produced would be largely the same.

As long as the diameter is the same I think the only difference would be in material used and build quality.

Maybe a slight difference in volume depending on wall thickness? Even then, wouldn’t be much.

Anyone with a 3rd cat delete tell me what/if warning lights were thrown up?

None at all in several months.

For anyone considering a full sports exhaust I would suggest trying a simple and relatively cheap decat with the standard silencer first. It makes a big difference to the sound and personally I certainly wouldn't want it any louder.

I've got a back box mod and the valves fully open and wonder if cat delete would be too much

 

[Magicman]

This is why I asked btw

 

[silent cilantro]

Yeah not sure why Milltek say that. The stock catted pipe has no sensors. It is downstream of the o2 probes.

Yeah thats what the guy said when he did my back box. I might give it a go, not a huge investment if it turns out to be too rude

This is the route I'll be taking personally. Cheap 3rd cat removal and my own valve controller.

I ordered the Milltek in anticipation of eventually getting the Emira. First mechanical change I’ll make when it arrives.

Does anybody knows we’re the OPF is located? Is it located on/at the 3rd cat? What does the 3rd cat finally do?

There is no OPF, there is a primary catalytic converter located on each bank of the V6 coming off of the headers. Finally there is a secondary catalytic converter with no upstream or downstream oxygen sensors that Emira / Evora owners often call the "3rd cat".

2x Red = Primary Cats
1x Green = Third Cat

Blue is the downpipe which combines both bank's exhaust flow together and merges to a resonator and then to a single pipe that feeds into the 3rd cat. You can slightly see some of the sensors in this photo as well, there should be 4 oxygen sensors total, 2 in each primary cat, 2 after each primary cat.

Finally to address what the third cat does -- it reduces emissions -- something this aging drivetrain has trouble with.

Watched this earlier too. Such a cool car! And yes, it sounds amazing. That 13k rev limit doesn't hurt.
