ASTRA H VXR MOT FAIL! EMISSIONS ISSUE AND DEMODIFICATION!

[@DaveReevesVXR]

Thanks. Seems to be a common consensus - getting a new main cat needs to be on my agenda!

[@markrs59]

Pre cat only need to present when car is first registered, removing it will make zero difference to your emissions if you oem main cat is still there, mot tester is clueless, your main cat is probably staring to break down and fail

[@chrissingleton8473]

pre cat won't fail it main cat will be fucked thousands a vxrs run without pre cat

[@debbie-gg3cv]

thousands more run without a main cat aswell 🤣

[@DaveReevesVXR]

Love it!

[@chrissingleton8473]

@@DaveReevesVXR yeah but it ain't pass Mot

[@markrs59]

Mine ran with no cats and passed mots no problems 🤟​@@debbie-gg3cv

Most emission failures are blocked cat ...lamba 1 or 2 ...open air filters ....exhaust leaks and air leaks .. Other side is oil burning past rings ... Or find a decent tester 😂

[@DaveReevesVXR]

Thanks. Hopefully no issues with the piston rings🤞🏼!

A precat delete wont be your problem it will be the main cat/sport cat has failed. Happened to me and has a new 200 cell sport cat welded in.

[@DaveReevesVXR]

Interesting… thanks. Will definitely keep that in mind for next year’s MOT!

That tester knows the emission system from the factory has visually been tampered with , so fail !

[@DaveReevesVXR]

I wondered if he would have noticed if the emissions had passed?!

[@mike-s8n8y]

Depends if he is an experienced tester , seen a few of these with defouler pipes fitted at the rear 02 .
