Title: Decat pipe into custom cat
Post by: benmanc on 04 July 2014, 08:34
Basically I have one of the decats with the decat section that drops out with flanges at each end.

I am looking to get a custom section made from my old exhaust cat so I can swap it out for mot.

Anybody done this?

Looking at it I think I would need...

Old cat
2 x 3" flanges
2 x 3" to 2.5" reducers
Guy with tape measure to weld it all together

Thoughts? Advice?

Hurdy did something like that with his Mk5 ED30

Might be worth checking out his project page  :smiley:

Surely somebody must have done this?

The amount of people running decats surely not everybody swaps downpipe come mot time if doing legit?

I think most people will probably know a "friendly" MOT tester, or will swap it once a year. As Rhys said, check out Hurdy's thread.

No but you posted up something about a mk5 which is a different car. Looked at the project page of his and mentioned nothing about it.

Same rules apply no matter what car is it  :rolleyes:

And I know 100% that he did exactly what you are attempting to do.  Maybe drop him a PM........ :whistle:

Its in his list of mods

Looks like the thread about his decat was lost when the forum crashed a few years ago

I've got a decat pipe into a custom cat for my 1.8T . My mate owns a custom exhaust business and done it for me if I ever needed it for MOT. Maybe worth trying a custom exhaust place if you have one near you.
