Guys,

On my old GTV V6 I put a straight through Ragazzon centre section on, and the noise level was perfect.

Now though. Im confused. The GT 3.2 exhaust is the same as the GTA system. And, from what I can see, has four cats in the system. Two of which are in the centre section part of the exhaust.

So, if I put a straight through centre pipe on her, I'm therefore losing two cats, and into failing MOT's etc etc?

Am I talking sense?

What do I do?:confused:

You just change the centre section which is after the 2 main cats. Your only losing silencers.. not cats. :)

I know where you mean, and I too thought there was only two cats just after the manifold on these engines.

But supposedly, the two boxes in the centre section are cats as well.

Anyone know?

There are 2 cats just after the manifold, yes, but then there is another section (aka the centre section) with 1 silencer.
I've got a straight through centre section and CSC rear silencer and it's not too loud and retains all the cats.

One silencer per pipe? That's what I can see.

Anyone got a pic?
