How many catalysators???

[YoGiS]

Well after mounting my sports catalysator in the Marea 1.8 I noticed to my surprise that there was not only a box in the middle after the cat, but there was also another box after this one, a smaller one that looked like a cat also actually, and then followed by the back box... What is this?? How many boxes, cats , or whatever does this car have??? HELP

Another question!!
Where is the lambda sensor in the 1.8 Engine (Marea)????

It's just an extra silencer!
I had a powerflow custom exhaust made on Tuesday and had mine removed

Yogis, you will actually find 3 boxes along the exhaust line.

1 small silencing box, followed by the catalyser and then the main silencer box which is at the very end.

Strip of everything including the manifold. Get a four in one manifold with a straight till the very ed, interupted only by the smallest silencer box you can find and in the end a big bore exhaust. Forget the catalyser...it robs power.

Hey ShumaniaC

The thing is mine seems to have 4 things!!

I have a Supersprint 4-2-1 manifold, followed by a sports catalysator i put, then followed by a box, then followed by a smaller weird looking box, followed by a back box!!! What the hell!!!!
Also where is the lambda sensor!?!?!

It will probably be just a small expansion box.

The lambda sensor should be before the cat, easy to spot as it has wires going to it.

Well all of these boxes need to go as they are robbing my Marea from precious HP
Another discussion is if it is ok that the car is now down to 850-1000 RPM in idle...is this normal and ok for the engine??? At this speed you can really hear the cams effect hehe

Re: Re: Re: Re: Re: How many catalysators???

You won't get a good idle with those cams. Fact of life.

I doubt the boxes are robbing that much power, a bad straight through exhaust will rob more.
