i have removed all 3 cats

i had my car on the dino and it done absalootley nothing not a bhp or a gram of toque.

just a new rasping sounding exaust and a light the come on evry 4days after i cleard th code

thinking of going for a 6 branch manifold when i get the cat back exaust system sorted but is it going to do anything

De-cat will usually yield some results, more noticeable on a forced induction engine. I'm hoping to at least remove the pre-cats when I got for the SC. If I read correct and you are lpg'd I have no idea of what results to expect. I had a friend who went LPG on a brand new Subaru Legacy.. only to find the valve seats were burnt out at 12000 miles.. and was informed this would be a regular thing

you was told not to remove the main cat...............ah well

I read it earlier and i thought he made a mistake.....should of changed it to 2.


Naughty naughty!!!!!!!!!

Thats why I put my name down for one of Mr Prolex's Hi-Flow cats

which are ready and look fine & dandy..........not releasing them til i can confirm no orange lights come on & emission are MOT able this will be done next week

Thought that would of been done in the R&D stage.

read the words.........."not releasing them til i can confirm no orange lights come on & emission are MOT able this will be done next week"

"Reading the words" it says not releasing "THEM" as in plural-more than 1 so when tested,if lights do come on it seems the R&D is wasted as you've obviously had a batch made up.

cheers

a sample of ONE will never produce conclusive results Pete

They are made to tight toleraances and all the hi flow cats are the same. The only variances I can think of is lack of precats and n/a or s/c.

Thank you Matt.

the lights im not realy botherd about (it only takes 1 min evry 4 days to use the eobd tool untill i can make a o2 simulator) or the noise
it's just the gain was nothing! if id of paid mony for welded pipes to do the de-cat i would of been realy ******.

the induction kit didnt work either but that was nessasey for the lpg conversion.

so when you say it never worked...............

do you have before and after dyno results?

and it all goes quiet....
