[Mk2] [NA] Japspeed Exhaust

[allsop83]

Hi Guys,

My little bro has just fitted a Japspeed back box to his N/A Rev 2, problem being that this system by-passes the Cat.....

......what do you guys do with the sensor for the cat when you go de-cat?

Cheers,
Chris

Anybody??

Are there two cats in an N/A ?

You had better be careful incase it now fails the mot, best to keep the standard exhaust/cat (until you find out anyway).
For the sensor either tie it up somewhere or remove it but leaving room to rewire it if needed.

only one cat on an na,

manifold then mid-pipe then cat then exhaust box

No, there is just one cat in the N/A (unless there is maybe one in the manifold...not sure) but that's not a worry now- easy enough to throw on the standard system once a year.

So having it just tied up somewhere underneath in a polybag will have no adverse effect to the engine etc.?

i think all the post cat sensor does is check the cat is working so wont have an effect on the engine, may bring a fault light up though, which can be found on almost every de-catted car in the country

Cool, cheers guys!
