De-cat Diy.

does anyone know if it's easy or not to de-cat the orginal exhaust??

i.e. smashing out the cat?

Once it's off it's easy....it's getting it off though that can be a right pain in the ****!! quite often the bolts etc are seized :(

With them tightening down on emissions... again... it might be an idea to buy a de-cat pipe, and keep your original cat for MOT time. A new cat will cost you more to buy than a de-cat pipe will!

Just my two pennies worth.

Oh... and I have the Aussie de-cat pipe.

I know someone who has a Rev3 de-cat pipe in stainless made by Amber Performance. I think he only wants £100, and it's never been on his car. He has a Rev2 and never fitted it... and never sent it back either!

Doesnt a downpipe replace cat anyway?

[Bibbs]

Mine was smashed out by a garage .. took about an hour apparently ..

Ive heard of some just falling to bits (inards, not the whole thing :D ) when you remove them...

You never know your luck.

The hardest part will be getting the bolts off so make sure you have replacements just incase they snap

[KiwiMR2]

Quite often the head of the bolt snaps off.

Yes it does.

But you can simply 'gut' the standard cat so it acts as a straight through 'de-cat' pipe. Some will say it acts like a swirl pot and help gas flow.

A de-cat pipe does replace the cat... but you will still need a cat come MOT time to get it through. If you gut your standard cat, then you'll need to get hold of a new one for MOT time. It's not a reversible operation!!!

Unless your car was built before 1993 then its not compulsery

I wouldn't be surprised if they brought out some crazy law that all cars built whenever, had to have a cat fitted...

I've been told (And do stress, only been told)

That Tubbies arent on the Emissions Database, so you can get away with a de-cat ;)
