de-cating help!

[jamie_pyrite]

Hi all, need new exhaust system for my Jetta but not bothering with a stainless system.

At the moment, it has a Cat, but it's a '91 so legally I can remove it!

I went to order a new system but order the straight through, rather than the cat. He said the straight through version is totally different - The cat version (1.6) is the same layout as the Gti, but is obviously a smaller diameter.

How can I get around this? What would I need to buy to replace the cat? Cheers!

local custom stainless place will make one.

Just fit an exhaust reducer at both ends Then you can use whatever you like for the straight through.

It doesn't even have to be a performance part, a plain simple piece of mild steel or stainless will do the trick.

Where are you based, I've got my old 8 GTi centre box going spare - yours for £20 if you want it.

if your jetta is an 8v then the end of the downpipe should be the same diameter as the 1.6 driver one.

i found this when i fitted a 8v gti manifold and down pipe to 1.6 driver mk2, the pipe where the centre section joins the down pipe was the same size.

i think its only 16v which has the bigger diameter exhaust?

A cat on a 91 Jetta?

Seems somewhat unlikely, although not completely out of the ballpark.

What's the engine code?

Cars registered after August 1992 must have Cats.

You can de-cat yours no problem.

I thought the 1.6 diameter is slightly smaller than the 1.8 Gti?

Don't fancy getting a bespoke pipe made up as it costs! Trying to find a pipe that is the right length/diameter but has the tapered (right word?) ends

wasn't it an optional extra?

my ED1 had one as standard

but it was a german car where it was legal from 1988

now removed with a 4 branch and a stainless system

Do what I did and rummage around in the skips outside your local fast fit or whatever, one mans trash is anothers treasure and all that.
 Cost me buttons to fab up my system for my old driver(I bought an ashley back box), painted the lot with hi temp paint lasted the life of the car. Used bits of volvo pipe amongst others, sounded unique (in a good way) too
