Do you get good gains from de-cats.... i.e.down pipe, center section and up pipe??? on a classic?

 

Indeed you do mate, definitely worth doing, i'd say get a remap after though

 

you get massive gains mate. you have to get a remap straight away with it. would recommend doing it mate

 

Unless it is a pre '95 import you will need at least one cat in place for MOT emissions pass.

 

Cool cool thats somethin that i will be sorting out soon then hopefully... Any ideas who does the re maps in the london area??
Its on a '2000' P1.... MOTs are only valied for the time there @ the test station... you could drive down the rd and something could fail even though it was all good at the test station ..... Plus i don't mind removing and re fittind exusts for MOTs thats no problem

 

I'm well aware of how the MOT works Knighty.

I actually reported my VTS operator to VOSA this year as he new less than i did and was an arshole about it.

I was mearly advising you of the fact that, you would have to swap once a year to gain a pass.

 

Hi, i have a 1993 import, the " turbo up pipe" has blown/cracked.

All of the replacement parts i have seen on the internet all say "De-Cat" on them.

Is there a Catalytic converter in this piece of the system on my car? and do i need it?

where else do i have them? i think it might be worth replcing the whole system but unsure if i need the Cats or not.

New on here so any help would be great.

Thanks

 

I'd recommend Duncan (race dynamix). he did my set up - well happy with the performance and he's a good chap to talk things through with

 

1993wrx there is no cat in the up pipe on a 1993 wrx. there is just one big one in the downpipe.

 

Thanks very much for the help dj219957 , thats great news.

Is it necessary to remove or drop engine mounts to replace this part as i have been told that i need to.

Apologies for what i would imagine are deemed silly questions but as im doing this on my driveway the more info i have before hand the better. lol

 

No worries dude, i don't mind getting me hands dirty 1nce a year lol .... yea i get you about some testers/mechanics out there that think they know absolutley everything

 

Drop the d/p and the driver side header, then pull and turn the up-pipe out from undernieth. Mine was the OE one with all the heatshield and sh1te on it, but the replacment was just a pipe so went back in loads easier.

You can attack them from the top, not much easier as you have pull the Turbo and related bits.

Just get a pair of ramps and take your time.

And don't foget the new studs gaskets, you 'will' need them.

 

Excellent advice, thanks, its on stands at the moment so will have a go over the weekend then.

any advice is welcome or other opinions, glad to be a scooby owner now tho,
