I'm after some advice on my pfl auto legnum which has a couple of issues.
The hot side turbo piping is larger diameter,aluminium and not the best fit as shown. Does this create lag? would I be better off with standard pipes?
Also there's a vibration as it changes 2-3-4. Possible issues are - Tailshaft seemed fine on inspection but there's an occasional slight clunk when putting in D & R. Or trans/tourqe converter. It came with solid engine mounts and sayc installed.
I purchased the legnum from Sleepyvr4, I was aware of its issues before purchasing and am extremely happy with the deal. Finding it difficult to contact previous owner-does anyone know this vehicle? Has it been tuned/dynoed? Output?
Visual mods are: big exhaust as in pics,varex,hdi ebc,lowered,ralliart dampers,rays volks and previously mentioned items.
Any information is much appreciated :).

Not sure if you have Pros or local made y pipe and front pipes but consider this:
1. You have what look like tuned length front pipes which are rare
2. Custom y intercooler pipe which is also rare

Intercooler and piping size increase adds lag but not very noticeably. Piping alone won't have significant drawbacks but will have noticeable improvements.

Clunk and vibration in gear changes sounds like a gearbox issue. I have solid engine mounts and only get extra vibrations at idle.

Edit: The y pipe is definitely not from Pros Engineering

Yes, the mounts seem to most cause vibration at low idle and is possibly amplifying an issue with the driveline. Trans fluid was pretty disgusting when flushed.I have a good low ks spare trans, suppose I should change this and remove/check tailshaft more closely first.

I am in no way trying to bag out some1's product. I have heard those ally pipes rub on the bonnet. Maybe this could be ur vibration? U can see the rub marks on front turbo pipe,

The exhaust is from Windsor Exhaust and was on the TME legnum. Maybe ask Steve if he's ever tuned it

Considering the oil condition that you found and judging by the symptoms, it sounds like the clutch packs Are worn.
