Ahhhh!!! Thanks Nippymog......So now I have to think about changing that cat or de-cat also....:-)

If one would take the cats away do you think the ECU will go bonkers?

Thanks

I understand that others have removed the cats without any ECU problems.

It's a long time ago, but I once spoke to G56 about the merit of removing the cats and they said that it made surprisingly little difference to power output. 2 or 3% from memory.

Your's appear to have largely removed themselves so you may as well help them on their way!

Thanks Bunny!! This is the first time my car "repairs" itself......:-)

Maybe I should still rework my original exhausts then until I decide on which aftermarket system to buy........I have heard the G56 system and it sounds great!! But I think they are way too big........

Personally I like the Demand Engineering look better but I have no idea on how they sound....Anyone that knows?

Thanks!

As Nippymog says, that looks like the catalytic converter has disintegrated. If you look up the tail of the exhaust header pipe you should be able to see the end of it, it looks like some rolled up crinkly cardboard packaging. If the one side has gone I would be tempted to remove the cats entirely from both sides, others have done this without issues. There is no material like this inside the standard Morgan exhaust, only very restrictive baffles. The quieter and free flowing G56 system does have material inside them as they are absorption exhausts.

Thanks for the info Planenut!!

I will go ahead and remove what's left on both cats and drilling the baffles to start with and then see if I like the sound I will end up with...:-)

Cheers

That is your best and cheapest option. I left the Cats in my pipes and just cut out the single blanking plate in each side with a 44mm cutter.
Sounds good, runs good, cost £3.40 for a hole cutter. I am happy with this same as Lee. The G56 kit is way too bulky for me.

Hi All

I am very happy with the pipes made from me by Custom Chrome and incorporating the well known "Cherry Bomb" silencers.

The person to contact there is Nigel Swift.

Hi KBMOG,

Thanks for the info....I also checked the whole thread!!

I will start by taking out the cat that's still there and then drill all baffles....and the considering a real rework with a local exhaust guy or buying another system.

Can you post on how your cherry-bomb system looks?? The pictures in the thread were not showing!!

Cheers
