So I got annoyed with the angle of the muffler.. altered the mounting points and managed to make it a bit more level and centred.





Car is definitely showing wounds of changed mounting points etc.. but oh well.

I miss the old nylon straps!

As fetching as they were, I think the back box would have swung about too much.. otherwise totally perfect!

Function over Form!

The sum total of an hours work...



Cut one of my 90 degree bends and straightened the end of the muffler.

Bit annoying that the 3" piping I've bought is not the same diameter as the 3" exit from the muffler! Oh well..

Pipe is specified by ID (inside diameter),tube is specified by OD (outside diameter).  It's a common cause of such mismatches.

Damn.. oh well.. it's a few mm here and there, I'm sure there are other things far more power compromising about the place.

Finally finished tacking together the exhaust!
Now to either find a proper welder person or risk it myself..

Go with a pro - you'll be so glad you did.

you only learn by doing... Gowaaan have a go.

Found a tig welder local to me that charges £75 an hour .. no back purging though. Think I'll take the whole thing to them!

Normally yes- but it's taken me I don't know how many months to get to this point.. me doing it would likely add on another year.

I have a question for you all on the placement of O2 and Wideband sensors.

Where and how many?
Do I need to run:
Pre cat 2x
Wideband (precat)
Post cat (pre muffler)
??

Or do I just have one pre cat bung put in, wire the o2 sensors into one and swap between the Wideband and O2 sensor as needed?

I haven't gone back through your thread:  What ECU arrangement are you going for? 

Quote from: Carolyn on November  8, 2023, 16:40I haven't gone back through your thread:  What ECU arrangement are you going for? 

I'm starting with the Emanage ultimate...

So you have harness that lets the Emanage do all the running of the engine?  If so, you only need the sensors the Emanage requires. The Speeduino we used for the supercharger car needed wideband, inlet air temp, coolant temp and manifold pressure, as I recall.  The O2 sensors were redundant.

Yeah I have the harness. In terms of "requires" this is where I'm struggling. The "car" normally requires the two O2 sensors, the Emanage can use the wideband sensor.. but if it's an either or both I do not know.

I guess worse case scenario, I get two bungs put in pre cat. Then if the setup requires 2x O2 and 1x wideband I can link the two O2 inputs to one sensor and run the Wideband at the same time.. I go with that.

Cheers!

Yes, but if the Emanage is doing ignition and fueling, any sensors feeding the car's ECU are redundant.

Does that apply to open and closed loop?

Again, if the Emanage is doing all the work of running the engine (fuel and ignition) the 'open and closed loop' relating to the car's ECU does not apply.

Got it.

So this is what it looks like the bumper on.. might create an angle on the end..




Have taken the whole thing to EMP performance. Who whilst not directly looking at me in a way that kicked my pride in tacking this thing together into the far distance, have accepted the job. Hopefully will be £150 well spent!

Got the exhaust back today- glad I did it. Thank you @Carolyn .

I had a second O2 sensor put in, but space is tight so I might need to find some kind of stubby or right angled O2 sensor.

I know you know this, but in case this knowledge is somewhere in the back of your mind .. remember the Emanage is just a piggyback. 
Your stock ECU will still need all the stock sensors and valid signals from them or it will cause havoc.

It's a decent enough solution but as we all know, it's more of a temporary solution. The Dastek is probably the best piggyback but unfortunately it's an absolutely fortune for the software, support is nonexistent and nobody will touch the stuff (save 1 or 2 outfits here).

Cheers Patrick- do you think the standard O2 sensors will give decent enough readings with wires combined (2->1) using a 90 degree sensor spacer?

Going to have to re weld the bung at the current rate..

I think a similar trick was employed by those using the PPE exhaust, to split one sensor into two outputs. It makes it less effective as you're only ever reading the combination of both "banks". But should be fine for your purposes.
