Thanks for the info, I do like to make things myself but I will give them a ring to see. Did they bring up any errors after fitting.

The Inlet flange is 3", it drops down to 2.5". You'll need the equipment and tooling to make a ball jointed end piece (flare out and then round back in) to mate to the center section unless you just cut & weld.

There's no O2 sensors in the secondaries.

I bought a used set of standard cats off ebay. Cut the cat' section out and replaced with a straight section of stainless pipe.

Like Stuart said, the ball joint and the flange would need fabricated and I couldn't be arsed with the faffing around.

I picked up the used cats for about £100 for the pair of them.

Well worth doing, just for the noise
