Pre-cat. . . . . REMOVED!

[skard]

Will have a look at doing this soon on my mates ramp 

[Meallbhan]

Thought I'd post up my Briskoda photo on here if it helps:

                                                                               I'm not understanding exactly how the standard exhaust separates.  You undo the four bolts at the turbo to release the exhaust, thats all good but then do you take the whole exhaust off, do you split it after the main cat, or does the pre cat come off the exhaust by itself?  I've seen a couple of photos with the precat on its own, but how does it come off?

There's a sleeve connection between downpipe and catback. It has a couple of bolts which are usually rusted and I had to cut them to separate dp from catback. After unbolting it, you just push the sleeve over the back section and downpipe drops down.

Thanks, I have seen the sleeve connection after the main cat (towards the back of the car, where you would put a cat back system on).

So the whole front section has to come off like in the pic above and its not possible to remove the precat by itself?

I suppose some exhaust paste would be a good idea when putting the sleeve back together?

Yeah the DP and Main cat is one section, (quite long, bad design) so take it al off, then just knock out the pre- cat, these is pics of mine.





Good luck...( you wont need it, easy as hell)

So what did your guy say, does he know what he is doing now

Had this done today. Awesome mod. Pulls really well higher up now, turbo spools up quicker as well

Only downside I notice is bad smell when sitting stationary for period of time, an reversing. All used to be stopped by pre cat I spose.  Anyway round this?

[Meallbhan]

A bad smell as in what? Exhaust fumes?

[Kinks]

If its an eggy smell isnt that a sign of your main cat has gone?

Been looking for someone in stockport to do it but no luck! The guy at audi doctor who is fab wanted to open the pre cat up and weld back together due toxins in material? Wanted £200 to do it :-( so anyone know of anyone in the area who isnt that cautious? Ill even provide a dust mask ???

Cheaper to buy a second hand Standard TBE on here, I bet there's loads about, smash it out yourself then take it to the garage.  Probably do that for a tonne all in, and an exhaust to sell on.

Not a bad idea wonder what price they go for? although if more money is involved then might as well look into a Miltek? does anyone know if the Miltek can mate upto the standard back section ?

The main cat sometimes makes that smell especially from cold. Most cars don't have a pre-cat so would have that smell anyway 

Milltek TBE doesn't have a pre-cat either so you would get that smell with that also.
