Decat how hard?
- Thread starter Gunny110

It's nuts & bolts to remove the cat, but depends on the bolts. When I changed the cat on my TDi some of the nuts where rusted and I could not get a socket on them so had to take a grinder to them. You then have to bash the internals of the cat out.
My son gutted mine for me,he cut it open,ripped out its guts and welded it back up.Didn't take long.

It can be done but I'm not sure how good it would be when compared to a proper decate.
Thing is, its free, so try it and see how you get on.
It can't hurt and wont damage the car.
I did the "smashy smashy" mod on my 1.8t got all the internals out as it's not actually fixed in place, just held by the Shape of the cat.
Definate performance increase but I noticed a little more noise over the proper pipe, suspect the gasses have somewhere to expand in there whereas a testpipe doesn't have that.

ive got a spare cat in the garage I'm going to get it cut open and gutted. I might try the smashing option first though.
on a side note... my old mk4 golf tdi I bought a decat pipe for £60 and took the original cat to the local metal merchant who then checked the number on it and gave me £95 :icon_thumright:
I was well chuffed

With great difficulty unfortunately... Lots of yanking and kicking the engine up...
with the front of the car on ramps,you should be able to wriggle the bit you removed through the engine bay,thats how I removed mine.

You can get at them you need an extra long socket, I also removed the wheel and the wheel arch liner and had that side of the car up on axel stands. It's not the easiest of jobs but it can be done. One other thing is to buy new nuts as no matter how hard I tightened them up they came lose after a few days.
I gained access to the nuts underneath, but the bolts themselves where moving aswel and I couldn't get a spanner on the top, so I gave up. Il try again tonight, but I have no axle stands as of right now.
You need to go in from the drivers wheel area over the driveshaft etc with a stubby spanner, if there anything like the ones on mine there a **** to get at lol but patience will win the fight !!
what engine have you got?Mines a 115 so the turbo is down,as opposed to afn for example that has the turbo higher.This could be why you can't get the cat out through the bay

It's a job well worth doing jb, I've only just done it and can already feel that she pulls more, not much of a change in noise or turbo whistle, but still I've only just done it. And regards to smashy smashy, I didn't even use a hammer. Just a large tent peg (10 mins) I would say do it.
