You'll need to remove the whole diffuser to install the exhaust.

I believe there are 14 fastners of various sizes to remove the whole diffusor. Then it should just drop away and you can work on your exhaust.

Yeah, the fins stay on also at least for the 12 and newer S cars the brace up under the tail pipe DOES NOT need unfastening, the parts manual shows these bolts to hold on the diffuser, when actually the bracket was modified to just hold the diffuser on with a slot. diffuser slides aft to release .. so end up as only 7 M8 hex head bolts and a I think 2 M8 button heads to remove. While sliding it aft and down you may also need to manipulate the metal sides out from the fender undersides. I would advice taping so as not to scratch the plastic, I didn't do the former so did the later.

This is a good general reference; but for the 12 and newer S's and ISP's it makes you take off too many bolts: http://www.lotustalk.com/forums/f170/diy-evora-exhaust-replacement-pictures-122885/#post1830161

Thanks Julian and Plackslayer...success! I imagine the extra red bit of hose that came with my exhaust is to extend the existing red hose to reach the valve, correct? Should I heat wrap the hose?

Interesting that my muffler also came with two extra clamps but have no idea what they are for....hmmm?

 

[Julian73]

Sent the PM reply on hose. Yeah two extra clamps, they are nice but heavier than stock. I figure on a well used normal car OEM clamps could be so rusty that they break coming off.

So I’ve had my diffuser off on my 14 S for a couple weeks while waiting for parts and free time and finally ready to put it back on.

So just to be clear, there’s no bolts that attach to the bracket above the tailpipe, it’s just a slotted fitment kind of like the engine cover (makes me feel better as I thought I lost two bolts). @Julian73

I was having issues test fitting it back on. Does the silver/metal kick up duct sit to the rear of the ARB towards the truck? And the sides of the diffuser closest to the front of the car sit up on top of the diffuser trim right?

So the whole diffuser should just slide horizontally forward until the 7 10mm bolts and 2 Allen bolts line up?

Thanks!

The local Lotus dealer is a Larini re-seller so they sold and installed mine. Larini crafts terrific exhausts; you'll love it!

There are 2 screws that go above the exhaust tip. I don't recall where the kick up duct ends up, but I can post photos of mine later if you need them. I remember having to be careful getting the sides slid into place to keep from scratching the side trim.

Mine has the bracket above the exhaust. But from day 1 it never had screws in it. Even before its first service.
I now have a carbon fiber diffuser mounted and since its lighter, I've never worried about the two screws.

Here's how the heat ARB heatshield positions when mounted:

@roarf A quick pic through the diffuser mesh would be awesome, or at least if you could verify if that front left duct sits on the backside or frontside of the ARB that would be great

@2011 chrome orange Awesome, thanks! Just to confirm, that’s sitting on the front side of the ARB closest to the front of the car?

Looking from the rear (by the exhaust) to the front of the car:

Or..

 

[2sblind]

Perfect, thank you very much. Now I know why it wasn’t wanting to go on right 😂

 

[2011 chrome orange]

There is ever so slight resistance as you put it on as the heatshield kind of pops in place against the ARB. You can feel it as it nestles in place.
