Hi

I've searched on the forum and can see a few posts that refer to this but haven't answered my question.

I have a MY2004 6 speed S RoW spec (New Zealand car). I have been looking online at several systems (Fabspeed and SpeedTech mainly), either a full system including the exhaust manifold/headers back or just the mid pipes and rear muffler box.

I have got a bit confused re what I should be looking at as I had a look at my car and from what I can see it only has 2 cats at the rear (just before the rear muffler box), it doesn't have cats just off the stock headers.

The aftermarket exhaust systems from the US all seem to have the cats (sport cats) sitting on the headers and the rear cats get deleted.

I'm unsure if I can use the US exhaust systems on my car as the O2 sensors are routed to the rear cats and if there would be a drama to route them to cats positioned further forward by the headers. Just got a quote for the Fabspeed system (glup!) it is expensive.....

Thoughts/advice greatly appreciated.

Cheers
