Header Difference

No worries. That Maloo sv340 system on eBay had a flange and Flexi from memory

Anyone know if a 2016 series 2 HSV Maloo LSA system will fit a motorsport and bolt up to the bi-modal mufflers? Is it 2.5"? System I'm looking at has flanges where it bolts up to the mufflers.

All VF utes Holden/HSV intermediate pipes have flange type connection that bolts up to the rear mufflers. Not a direct fit due off LWB platform. If you want direct fit to your motorsport, look for a LSA system off a wagon/sedan (SWB platform) as they have ball type like your motorsport and yes they 2.5".

The mid section of a ute system will be too long for a sedan/wagon, and the rear hanger location on the R/H muffler will be wrong.

Thanks for the info.

Bit off topic but does anyone know of any immediate danger to fitting long tube headers and cats without getting a tune?
Will be trying to save a bit on labour and fitting them myself the night before I drive up to BTA motorsports and get the OTR and tune done.
I expect it to chuck a code from the o2 sensors but will it ruin anything if I drive easy for not even 2 hours to get it on the dyno

It'll be fine.

It's not really a matter of time or km but the amount of difference your O2 sensors report. The long term fuel trims may be maxed within seconds or over a period of days. The check engine light may go on straight away because of rear sensor diagnostic, masking the main freakout of running lean.
Is it OK to drive an EFI car without correct sensor feedback, no. Will it kill it, unlikely if you drive like there's an eggshell under the accelerator but yeah there's no way of telling if you are fine or breaking the car without calibrated feedback.
FWIW I wouldn't do it without loading an intermediate tune to see you to BTA. Having said that I think most people don't really care or understand what's at stake. Why not see what BTA think, would make sense.

Fair shout, thanks for your input. Glad I asked now, I will give them a call tomorrow and see what they suggest
