View Full Version : de-cat question
Alreet fello clio members.
On my new valver i have a de-cat pipe, but i have been told i need the cat on it to pass its MOT which is due in November.
Are these easy to take on and off and what do i do when it comes to the MOT? Also, having it on, does that restrict the engine power?
Thanks

4 bolts to remove and swap it over. (new gaskets will be needed)
a cat does restrict engine power, a decat is like loosing a passenger :lol:

decat makes the cars much better .i doubt u will pass an mot with it u could try then if it fails u know u need to put a cat back on.its a easy job i used to do it in bout 15 mins...
or u cd find a dodgey MOT place that will pass it if u kno the chap who dus it or maybe if u slip em a bit extra :wink:
thats my plan any way :lol:

best thing to do mate is soak ur bolts in WD40 a few days before ur gonna take em off, usually makes it alot easier, then copper grease them when u stick ur cat and ur decat bak on!!!

Gaskets are a pile of crap........exhaust putty around the sealing edges works 100x better
true - but its not as neat as a gasket.
hate using wag to fix joins.

THAT MUCH :?:
remember the nuts are 1/2 inch if you use a 13mm there is a great chance you will round them off, use lots of wd40 as they do get very hot and the bolts snap.
They are?!?!?
I used a 13mm, and twas fine
