Title: Mk5 gt tdi 4motion de cat
Post by: kmackgttdi on March 13, 2014, 10:32:47 am
Hi folks. Just putting the feelers out to see if anyone near Edinburgh would be willing to remove the cat for me? I don't really want to spend nearly £300 on a pipe.  I was going to knock the insides out but having a look it looks like there is a right bend before the cat, I don't have a welder or I'd do it myself.
If you are willing please give me a rough price and thanks in advance.

The downpipe is quite a large part of the exhaust (roughly half) so yeah you're right. It's probably worth getting it de-catted rather than buying a full downpipe. Unless one comes up in the classifieds. Look at custom exhaust places around Edinburgh, Central belt. I got a backbox removed and a stainless pipe put in it's place (with twim GTI tips) for about £120 a couple of years ago. I used somewhere near Cambuslaing though.  :happy2:

Still only needs to pass smoke test with a cat? I thought the new change is for particulate filters?

No its a visual check also now-if it came with a cat from new then it has to be on

What if the exhaust is behind a heat sheild or other body parts, so that the MoT Tester cannot see it. Do they assume it is there, or assume the worst?

Only asking as the 170 TDi Catalyst is way way up beside the turbo, but you cannot really see it from under the car or under the bonnet.

Will be good to know for the future, although a nice shiney stainless downpipe might give the game away!   :rolleye:

Big shinny down pipe certainly will be a give away lol.  Wow I saw the change for particulates. Hadn't seen that. From what I know my cat is right after the turbo too.
Cheers for that.
