2nd decat

Just had my second cat removed, doesn't really sound that much lounder but the car seems more alive,

from looking down the exhuast the cat is PROPER thick, like a brick in the pipe, i've nevre seen a cat like it

As a N/a driver, does any one of our trader to a plug and play 1st cat decat pipe, just wonder how it would sound and pull, with out the first one out

To replace the first cat it is a full manifold jobby iirc.

You should have taken the first cat out instead, it has the same type of core but it's bigger (causes more of an obstruction for gas flow) and closer to the turbo's.

its an n/a

Oh well, that will teach me not to jump straight in with the finger typing and read the full post first

Nothing to see here . . . . . . just carry on . . . .

Have one sat here for a while...........

just wondered if there`s a sensor in the first NA cat?? anyone?

while you guys are on the subject, ive just recieved my xs power trd style cat back exhaust for my NA. Doesnt matter how many times i read up about cats first and second and decat i still dont understand it.

I have 3 sections delivered today and ive been readin up all day about this exhaust.

Is the 3rd section needed at all?

Also the car is being mot'd in few weeks and heard that it wont pass with both cats out or something.

any help would be grateful!

My friend is fitting it tomorrow as im not technically minded as you might have noticed! :-)

think there`s a clue there in `cat back` !

ie from your 2nd cat back to the exhaust tip,

also fwiw mine with only first cat in place passed mot ok.

the xs power cat back exhaust normally comes in two pieces so if you have 3 pieces one of them will be a decat pipe to replace the 2nd cat! if you dont want to decat it pm me and i may take it off your hands!

wot difference will de-catting it do? ill take a pic of the bits n you can tell me which is the spare one as am clueless. I just know ma old exhaust is full of holes n the xs exhaust comes highly recommended :-)
