scotty435 Posted February 13, 2019 Report Share Posted February 13, 2019 Can anyone confirm if the deletion of the 3rd cat on a NA Evora worth the effort and where is the best place to get the replacement pipe ? Quote Link to comment Share on other sites More sharing options...
Popular Post Del Lardo Posted February 14, 2019 Popular Post Report Share Posted February 14, 2019 By all accounts it does make a difference as it removes some unneeded restriction but I did mine same time as backbox so hard to quantify. I think I have one knocking around in the garage if the new owner doesn't want it. Yours for postage cost and a few £ in a charity tin of your choice if you want me to check? 3 Quote Link to comment Share on other sites More sharing options...
Registered Posted February 14, 2019 Report Share Posted February 14, 2019 Yes worth doing at its relatively cheap price. Just don't expect night and day improvement in sound. The exhaust note will improve by approx 20%. It also saves a little weight. 1 Quote Link to comment Share on other sites More sharing options...
Gold FFM andyj007 Posted February 25, 2019 Gold FFM Report Share Posted February 25, 2019 ive just done mine this weekend... i have the sport back box already.. noticeable difference (better) if i didnt have the sports back box already i woud have got the tubular back box with the decat pipe in place , that sounds really good. (Although £800) this still keepe the the front two decat pipes.. i heard this on @m6arks car at the weekend.. it straight forward enough but i had to grind off 4 diffuser bolts due to the hex heads rounding off.. 1 Quote Link to comment Share on other sites More sharing options...
electro_boy Posted February 25, 2019 Report Share Posted February 25, 2019 I'd say 3rd cat deletion is worth it. I've been to a couple meet ups and my Evora seemed to sound a bit louder and have more crackles in the overrun than some other cars. As far as I was aware I had the standard sports exhaust on my car but found out on the weekend when I had my diffuser off that the cat was missing and replaced with a straight pipe. I guess this is the reason my car sounds different to other NA cars? 1 Quote Link to comment Share on other sites More sharing options...
Popular Post Del Lardo Posted April 2, 2019 Popular Post Report Share Posted April 2, 2019 As a few people have messaged me, Scott did take the Decat, my garage is slightly emptier and a charity has received a generous donation. 3 Quote Link to comment Share on other sites More sharing options...
LotusFella Posted February 23, 2020 Report Share Posted February 23, 2020 Hi all what are the options for a decat. I have 2010 S. I know 2ubular do one. Anyone else and how have the performed? Thx Quote Link to comment Share on other sites More sharing options...
electro_boy Posted February 24, 2020 Report Share Posted February 24, 2020 3rd cat delete, is literally replacing the CAT converter with a section of pipe with some flanges. If 2bular don’t have one then I’d just try any local exhaust place. It’s not rocket science and any exhaust fabricator should be able to make that up.

EGTE Posted February 27, 2020 Report Share Posted February 27, 2020 I find my 2bular a little TOO loud, to be honest. Thinking of going back to standard (Sports exhaust) Must be getting old 🙂 Quote Link to comment Share on other sites More sharing options...
Gold FFM Popular Post EuropaSman Posted June 9, 2020 Gold FFM Popular Post Report Share Posted June 9, 2020 I just had a 2bular decat pipe fitted to my Launch Edition yesterday by PJS Lotus. As the Lotus Stage 1 backbox had to come off for a support rod weld repair, I had the third cat removed. I definitely think it was well worth the £170. 4 Quote Lover of everything Lotus Cars and proud owner of production Evora No.75 (2nd UK customer specced car by VIN).

cdco Posted July 9, 2020 Report Share Posted July 9, 2020 @EuropaSman looking at your pics made me realise there was something off about my car ....

So fixed tonight again TLF has helpful info it doesn't realise it has 😁 1 Quote Link to comment Share on other sites More sharing options...

Gold FFM Barrykearley Posted July 10, 2020 Gold FFM Report Share Posted July 10, 2020 This thread has prompted me to consider doing mine. It’s already had the Intake kit on it - so I’ve just got the torch out and had a peek underneath the tray - 3rd cat delete pipe already present 1 Quote Only here once Link to comment Share on other sites More sharing options...

scotty435 Posted August 8, 2021 Author Report Share Posted August 8, 2021 Not sure having never had a 2bular fitted to any of my Evora’s. All I can say is the Janspeed and decat is a great sounding combination without being to load. 1 Quote Link to comment Share on other sites More sharing options...
Gold FFM Alfa2Evora Posted August 8, 2021 Gold FFM Report Share Posted August 8, 2021 @Celica This is my NA with decat pipe and 2bular backbox (valved but with valve closed) if it's any help - I know videos, especially when the camera mic' is not at its best, are not a true representation of the actual sound but it gives you an idea : 1 Quote Link to comment Share on other sites More sharing options...

If you want to take further still, next stage would be to add a CAI, adds an extra level to drama without making it too loud. Quote Link to comment Share on other sites More sharing options...

Gold FFM Cdm2018 Posted August 9, 2021 Gold FFM Report Share Posted August 9, 2021 I think trying to find used BOE will be hard or rare ?

Quoting an old post, but if people had a choice would it be oem lotus sports exhaust and decat 3rd pipe or a non valved 2bular; for liveable noise and excitement ?

Gold FFM EuropaSman Posted January 27, 2022 Gold FFM Report Share Posted January 27, 2022 @Ahmad B I had a 2bular decat pipe fitted to my Launch Edition in June 2020. See one of my previous posts above ^. No issues at all after the 3rd cat was removed. No MIL light.

The post cat O2 sensors are located BEFORE the third cat; so removing that one will never cause a check engine light. 2 Quote Link to comment Share on other sites More sharing options...
