2bular NA Evora Exhaust System

I received the last pieces of my 2bular NA Exhaust System today.
You can see the "PreCat" O2 sensor ports in the Header Collectors, and the "PostCat" Ports on the distal end of the Metallic Cat.

I'm anxious to get them installed, but it may be a couple weeks, since I'm waiting for my new 2 post lift to arrive, and I've got a couple races coming up.

I'll post photos of the install, along with before and after Dyno data.

Very nice, Don!

The Evora's have come a long way from having nothing available.. Now we got an awesome CAI, several of exhaust upgrades...even a couple of supercharger kits to choose from.

It's only a matter of time before someone offers an engine swap solution!

I had this installed a couple of weeks ago. The sound with the radium CAI is amazing! Which cat did you get from him?

Hopefully there won't be a proven S version come along. My vow not to mod would be seriously challenged.
And please, no CAI either!

I got the 200cell Metallic Sports Cat.
I think that is all Jim is currently offering.

I think Jim at 2bular has the Larger Diameter S System pretty much finished.

That's a start. But thankfully (for my vow to remain stock) there's plenty more to do. Incl ECU "experiments"

Sarcasm aside, this is an exciting prospect. Even though there is a lot to be said for the grown up stock sound.

I think the ECU tuning should be done AFTER the Exhaust System, to optimize the benefits of each.

I'm not as interested in the sound as I am in the 30 HP to be gained. Having said that, my stock NA Evora is SO quiet that sometimes I have to look at the tach to know when to shift.

I think you'll be very impressed with the combination of that exhaust system and a sport muffler. The sound will match its looks

I was talking with him about it and he did a 100cell cat for me. Jim is the man!

I noticed there is an o2 bung on each of the 2bular header manifolds, I thought these were removed and instead, the o2's were extended to be placed onto the cat?

1 upstream and 1 downstream for each cat's element.

The 2bular system sounds evil, yet, beautiful in conjunction with the Radium cai and the Janspeed muffler.
