Right....I tried this already under GTT forums without much success

Can anybody tell which cats can be bolted on to the GTT manifold as-is without custom fitting?

As far as I know, the one fitted to the manifold originally is made by Janspeed.

Cheers,
Sam

Not sure if this is right, but I think GTT do their own manifold and CAT see 240+ conversion and they also do Janspeed manifold, which they say are nearly as good as their own. I think!!

The standard cat that comes with GTT mani is def made by Janspeed. This is directly from the source...

But seems that not many haven been playing with their GTT manis/swapping cats - or just do not feel like sharing

GTT manifold requires GTT cat. Our manifold has larger secondary pipe than Janspeed and is TIG welded.

Thanks Roland!

What you're saying is that the cat is custom made for your manifold and fitting other cats would require some little custom fitting/fiddling?

EDIT: saw that you already answered the Q under GTT forums...
