de cat?

[dane]

what will this do to the performance?

[Mark51]

the cat restricts the air flow of the exhaust fumes so de-catting it means that the cat is no longer there so the is ALOT less restriction.
depending what other mods you have you will see a gain of 4-8bhp

well i have a raceland ram induction kit and a cat back scorpion system

[Robbo]

youll feel this difference like. i had a raceland filter and cat back... soon as i got it de-catted it went through the revs easier and just seemed faster lol

plus.... make your exhaust sound sweet ;)

[dane]

yh i think im on the case lol cheers

[Lee_P]

dont forget the mot issues with this though

[mrorange2]

great mod mate you will certainly feel the difference just remember to to swap back for mot lol

[dane]

it has been put on hold, i looked at my downpipes and the cat is on the manifold at the top, so ill need a 4-1 branch manifold :(

it is illegal to de-cat a vehicle registered after 1993 as it will fail its MOT emissions - translation 'do it, enjoy it and change it back for the MOT!'

my work here is done!

[jas16v]

i've had decat on both my cars..

and its made a big differance to both :D

Cat acts like another siliencer, and it basically restricks gase flow in the exhaust. Remove it and replace it with a decat and gas flow will be increased.

Don forget though your need it back in for MoT time.
