Janspeed Exhaust System

[mathew]

Hi, someone has bought "Janspeed Performance Exhaust System Nissan Micra K11" on rallynuts?

I want to know if this system is a "catback + backbox" or "de-cat + catback + backbox" ?

(Does replaces the original catalyst?)

TY

hi mathew

janspeed do a 2nd decat, so i believe it,s catback only, a stock 1.4 midpipe (catless) is an option

 

[mathew]

can someone please confirm? (who bought)

 

[curtis]

It must be a Cat back as that pipe isnt long enough to take out the cat and also not for that price

CATback + backbox only

Hi since this post is open can I ask a question(s)?

I've been reading about these janspeed exhausts and I would like to fit one, when I fit my 1.3l engine in the K11. However I’ve been reading about emission failures, and it not having the catalyst after the manifold, and only having the one under the car. Or is there a janspeed exhaust that has both cats? Or a cat you can buy to fit in with the janspeed system? I'm very confused I don’t want my car to fail its MOT when it next goes in, if the exhaust and that is in by then.

Any help, anyone can give will be great thanks.

Ben.

they usually just scrape through the emissions with the 2nd cat only ben (IF you can get/keep it hot enough)

 

[boltneck]

But if they do scrape through, what are my options frank?

Cheers,

Ben.

heatwrap ?, ecu remap ?

 

[boltneck]

Ok since ive joined this forum ive done my research into a ecu map, so know what that is in a nut shell, however i havnt heard the term heatwrap before.

Thanks frank,

Ben.

you know..... that fireproof tape stuff ben :grinning:

 

[boltneck]

Yeah, i have just been doing some searching i now know what it is, however i cant understand how it will help the emissions, or a ceramic paint. Which i now know ceramic is a better and more long lasting option, and i now also know that these janspeed exhaust are quite weak not cool, well the mild steel, but stainless steel maybe better, is this the stainless onehttp://rallynuts.com/motorsport/K11_Tuning_2084/Janspeed_Performance_Exhaust_System_Nissan_Micra_K11_3167.asp

Thanks,

Ben.

the heatwrap is to keep the cat warm ben (either around the cat, or manifold and cat)

 

[boltneck]

Hm ok then and now I know after more reading that a warm cat (which it should be when tested) is more likely to pass the emissions test.

Thanks frank cleared things up for me a little bit, ok a hypothetical scenario, which I do want to happen eventually. My car micra 1.0l K11 1998, upgrade the engine to a 1.3l from a S/SR, and I will find one that’s younger with less miles, an steal the gear box (as backup what ever, I just feel I want it to match, lol maybe I have a little OCD), from scrap. Install this re-built and a janspeed exhaust at the same time, heat wrapped maybe ceramic painted, best I can afford induction kit, and boost valve. In you personal experience what are my chances of scraping through the MOT. (an im not sure on the boost valve, seems ill need to get an ECU remap, which is what i want in the long run, before the boost valve is useable without drinking loads of fuel, not sure about all this yet)

I know I ask a lot of questions, but I've just been on a thread, an forgive me I forget his/her name, who said fact is best to help things be clear etc, I'm the sort of person who likes clarity, especially when learning new skills.

Thanks a lot frank, I'm enjoying quizzing you lol .

the g/box, clutch, shafts etc on the 1.0,s changed in 98 eh, which can complicate things for you ben, but my spare pre98 1.0 g/box remains unused, (and i,ve ragged the original one for 46k miles so far) :wasntme:

 

[boltneck]

Lol and now thats more hasstle, so anything out of a year 00 will cause issues, so maybe just stick to 98 and hope i get lucky an find a right off with engine an gear box in tact with less mileage than mine, though mine isnt to bad 71k so far. Very confused the more i read, the more things i can do etc, going mad lol.

Thanks Frank,

Ben.
