So here is what all my fuss has been about this weekend:

New Manifolds:


New Exhaust:


Test Drive:

Not an afternoon for the brave hearted or foolish - I gave it a couple of wee blast just to give an idea of what its like. I daren't go any further out of Aboyne... I think I was pushing my luck as it was.

Hopefully some of you will enjoy this. Cost aside (which hasn't bothered me a jot), I think its fantastic - Im really very happy.

Just not sure how to upload it on here! lol
Hopefully my technical incompetence will not prevail.... Falling which it will sound awesome at SpeedFest! Hahaha

Upload to your photo hosting service then paste a link back in here. If you don't have a hosting service, YouTube will prob do. Just need an account. I think you can make the YouTube upload link private only to those you give it to, if you wish.

Cheers Campbell..... Ive followed your instructions and the tech-guide and I think Ive done it?!

Enjoy!

Welcome to the club

Folk don't forget this is a FULL setup so that is decat manifolds, downpipes, 100 cell sports cat and a valved back box. The equivalent setup from Larini is nearly £4000 without fitting so closer to £5000 once fitted so definitely the 2bular is a fair bit cheaper.

Also Jim's system is the only 70mm setup made for the Evora/V6 Exige - everyone else has 60mm setups so the 2bular is the better breathing setup.

For people not wanting to splash the cash in one go or not go all out you can actually do:

1. Backbox
2. Backbox + 100cell cat
3. Backbox + 100cell cat + downpipes
4. Backbox + 100cell cat + downpipes + decat manifold

I love my setup, and I've been working with Jim and Craig for the best part of a year getting it right - that's 4 different backbox designs, 2 downpipes designs and a couple of different cats.

Cheers Saj - was just on the tip of my tongue to expand on my earlier posts - but Im still at the "can't quite believe the difference" stage. As was previously mentioned - its all relative, but the improvements (for me at least) are well worth it - and I know for a fact that I won't be alone!

I believe that it is actually THAT good. Arguably turns the car into what it should have been to start with - and finally gives the cars it (albeit loud) voice! I can understand why Lotus don't do it though - but their loss keeps people like Jim in business.

I believe it's a 9 hour install for Craig and the boys.. which is where a chunk of the money goes. If the weather ever improves up here I'll get the car out and post some videos... It's epic...

Agreed that you could buy a car for the same money - but I guess it's relative.. My Evora was bought new and cost a fortune, but I love it and enjoy spending some pennies on it

Its great to spend money on your pride and joy , why not. But that value for a small gain in performance and it making the car sound better not for me.

Each to their own and bet it sounds great , but for that sort of premium ... No thanks.

I'm really happy with it actually, and I think the gains are more than just subjective. Komotec quote good gains from their full system - and the weight saving is significant too.

I'm about to fit a new Carbon CAI and accompanying remap... Which should net around 400hp. Still cheaper than shelling out for a new 2015 face lifted Evora - and if I've got the money to spend then why not! lol

I'd rather try and make improvements this way than put a body kit or something on it.

Im not knocking your choice , far from it. Its about making the car your own.

Are you going to get it on a rolling road while the remap is done? Who you getting to do it?

I did it purely for sound, performance was an added bonus especially if you go down the komotec route but even without it going from 3 x 400 cell cats to 1 x 100 cell cat makes a big difference just like that.

Also that video along with my videos just don't do the setup justice. So frustrating to not be able to get that across in the videos.

Sounds epic, glad it worked out so well for you.

The Porsche boys wouldn't flinch paying £4,300 for a dealer fit PSE (the switchable exhaust) so not sure why there's such negativity for a hand built, custom fit, manufacturer sanctioned exhaust.

The Porsche boys are a special breed.

4k Think I need to give up writing computer software and learn how to weld

Sounds epic though and life is too short to be sensible

[renmure]

4k Think I need to ... learn how to weld

Ditto.

... life is too short to be sensible

But, Ditto again I suppose

Sorry for my technical ignorance, but I can only see three parts/steps Saj in Tony's two pictures. What's the difference between the down pipes and decat manifold? I thought that picture 1 was the manifold/down pipes i.e. same thing and picture 2 was the 100cell cat with the back box. Is there a 'Y' piece to be added between the two? Can you do the upgrade in the opposite order and would there be an advantage either way?

Also the quality of work on the exhaust looks superb but I would prefer the twin pipes from the back box.

Cheers for the video Tony, I bet that it would sound even better with the roof off in a V6 Exige too.

Totally agree... And to be honest I'm surprised and a bit taken aback by some of the comments. Life is too short and as this is now offered as a dealer fit OEM style option I can see a big market for Craig fitting these to brand new V6's before they go off to their new owners.

I'm quite happy to be a special breed too ... Buying into a brand which requires compromise and TLC, ahem...... Maybe it would be easier to be a Porsche Boy after all!

[anthonyyule]

Good point Steve.... Now I read that back.
I believe there is a link pipe joining the 2 manifolds before it goes into the back box.... But yes the big gain is from the decatted manifolds.... A pre cat on each manifold on the standard (and heavy) standard system which have been removed.

I've actually got a 200cell cat as Craig reckons the 100 cell would be marginal for mot time and I've got no interest in spending time changing it out just for the test. Performance drop for the 200cell was deemed negligible from both Jim and Craig for my purposes.

Saj - what's your thoughts on Steves query as I don't think I've answered him properly!

[Mikie711]

Steve what isn't shown in the pictures is the link pipe which is what I think they are calling a downpipe. It joins the manifolds to the cat. When I was working with Jim on the NA set up a couple three years ago we tried various sizes on the rolling road to see if different combinations made any significant difference, bigger isn't always better. And for the NA this turned out to be the case. We also started with a 200 cell cat but ended up with a double dip (they are dipped twice rather than the 200cell once) 100cell as the 200cell didn't deal with the emissions side to well.
If you do a staged upgrade then it would work like this. Fit new back box and 100cell cat, would need to blank the 2 sensor ports with this configuration as they aren't used. Fit new link pipe, now you need to extend the 2 post cat lambda sensors wiring so they can reach the 2 new sensor holes downstream of the 100cell cat, Jim was trying to source the correct plugs to make extension cables plug and play but I don't know if he ever managed to find any.
Next is the manifolds, these get rid of the pre cats and again you will need to extend one of the sensors wiring loom to make it reach it's new position or fit extension cables if available.

Clear as mud, oh and the front manifold was a pig to work out how you got it off the engine, it comes off from inside the cabin believe it or not.
