Just got the quote from the local very well regarded exhaust place.

Job: replace factory precats with new 100 cell cats. Delete centre cat and replace with X or H pipe in 2/12 inch stainless. Refit exhaust temp sensors. Fit up to my existing back boxes. All to be removable and factory system retrofittable.

Total cost AU$1800.

Both mine have had a custom straight through system (straight pipes). There are two sets of cats, the pre-cats (1) off the downpipes and then the centre cat (4) which doubles up as a silencer. It's dead easy to remove this centre section and replace with X or straight through.

The pre-cats can be replaced with Larini race pipes (no cats) but bear in mind emissions might be a real issue. I've just MOT'd the auto car and it scraped through so removing the pre-cats as well will be pretty difficult. Because of their proximity to the turbo's I would urge caution as when I tried to remove the pre-cats the nuts were seized on solid! The last thing I wanted was to crack the turbo manifolds!!!! Job put on hold for fear of damaging them and engine out job.

This is what the auto sounds like with straight through.

Tubi's and Larini's still have sound deadening in them so really if you want the full works then you need straight through and cat/silencer delete. Removing the centre on yours would be a start too but won't add a massive amount.

This was mine with centre off and standard rear boxes.

Will the cel be triggered if I delete front and mid cats? Any help appreciated thanks guys

What does it matter, it should always be lit on a 3200. If it isn’t, replace the bulb. :)
