To decat or not to decat, that is my question

[wongthecorrupter]

Thinking of decatting my 4 litre Tuscan,what are the advantages and disadvantages and where have you all brought your decats from.
Cheers

Advantages - Louder, Bigger more explosive backfires, More power if chipped for it, Gearbox doesnt burn your leg.

Disadvantages - Car stinks, Some say its too raspy, Its a bugger taking them off and back on for the MOT

Needless to say i run decat!

Was your car mapped for decat

[Djdan]

Apparently but without taking the ECU apart its impossible to tell. Barry at TVR Ecosse allways tells me mins sounds better with CATs but i like it raw..and smelly!

What's a cat mine came de cated so no idea what there like any other way :-)

[so called]

Mines decat with a decat chip from Dom complimented by Powertech cans and very shouty she is.
Sometimes I think of going quiet again and going all subtle but she runs so nice without.

As above, powertech cans, very loud, put the cats in for the mot the other week and its just not the same!

Also it cuts down the chassis coating and paint damage from the cats.

...quite as quickly.

Can you buy the decat eprom as a part or do tvr power just supply and fit

[m4tti]

Has anyone used under bonnet heatshielding to prevent the heat damage?

[Toady1]

Mine was mapped decatted, so if I put the cats back in it might kill them very quickly and reduce power. But I do find it too raspy without!

You find it raspy with the cats out

yeah ive got the crazing but before I get the bonnet resprayed I'd like to protect it without shiftin the heat further down the exhaust.

Fabricate some form of heatshield for above the manifold?

Thats effectively what the heat blanket on the underside of the bonnet will achieve with less heat radiation. But according Wong this isnt that effective either..

It hasnt worked on my car
