Oh really, well I have an X force cat-back exhaust and I could not pick 1 thing out that I don't like about it.. It doesn't drone, produces a good note and gives some good top end power. But in saying that, ive never also had any other after market exhaust brands other than X force installed, how did you find the exhaust from castle hill, did you notice any difference in power? Have you uploaded any videos of it, id be very interested in hearing what it sounds like?

I need a second opinion guys, I went to a local exhaust shop originally for some quotes for 2 high flow cats to be installed, and he replied that they would not do jack, and if I where to install the 2 as I apparently have 4 cats.. I would be getting a warning lights flashing up on my cluster or something along thoes lines. Is this really true?

Castle Hill exhaust have dyno proven exhaust systems, that's where i would be going.

You only have 2 cats, they are up near the manifolds, the ones under the car are actually resonators.

Unless you do extractors, there is no real need to replace the stock cats as they will flow fine, and then it is only because the stock cats are too big to go under the car because of their shape.

I appreciate your help Not_An_Abba_Fan, so if I where to change the cats now or latter on with a new set of extractors will I get any warning lights appearing from my cluster? Because this bloke who I spoke to at the local exhaust shop was bragging on about how my car's exhaust system will only operate with euro cats otherwise the ecu would be picking up all these sensor faults ect.. Is this true?

No, complete bullcrap.

Your O2 sensors would be what would cause those errors for your exhaust. If you changed them over, then you might, but that guys was just bullshitting you.

What usually happens is the paint on the extractors burns off and contaminates the sensors, this will make the drive train warning lamp come on, not changing the cats.

ahh i see..
In that case I am thinking about getting my Xforce cats fitted tomorrow, so I have a few other questions..
In what way will changing the cats, change the sound of my Xforce cat-back exhaust system? will it just make it louder or..?
I already know that the cats alone will only give me a couple of kw gain, but at this stage im only concerned about sound as I don't get my set of pacemaker extractors until July .
