Hi,

I've got a spare exhaust rear section with CAT from a MY01.

Anyone got any ideas how to remove the CAT leaving a stealth straight-thru pipe ?

Alternatively - anyone want to swap it for a straight-thru pipe ?

Cheers

Chris

 

Cut it out and weld it up... if your near leeds Ill do it for free for you... Assuming you find a bit of tube to replace it with...

David,

Thanks for the offer - but too far from Leeds - you've given me an idea though...

Cheers

David,

I'm surprised you just didn't tell him to bring over some scaffolding poles and you'd fabricate a new one

Hope your not letting your bodging standards slip

What you trying to say about me???

Scaffolding is too heavy, (To run off from building sites with that is )

Going to make a quickshift for less than a tenner tonight... and I aint joking..

David,

I never doubt any of your statements You're a credit to us all; stand up an take a bow

Having never seen the inside of a catalytic converter - would a power hose be powerful enough to blow the stuff out do you think?

Or perhaps one of the drill things for unblocking drains ?

Chris

 

Err no... dont do it..

 

I've removed a cat on a old car of mine, by taking off the centre section, basically smashing the ceramic internals out, basically a cat is a honeycomb (toxic) with pieces of gold in it, using a similar size pole straight thru took a while but once it's started to break up then it will start to come out a lot easier, may be worth doing it on a spare piece of pipe tho.

 

If you can get a long masonary drill ( a big 20mm dia preferably)you can easily drill most of it out. As the previous post states, once broken up the rest comes out quite easily followed by the steel retainer (in 2 parts).

Don't breath the stuff in, wear a mask and do it out side.

If you do just the centre section you probably won't notice an increase in noise. There isn't much gain in performance either until you do the same to the DP (but that's a bit trickyer to do...).
