VVTi de-catt

[Supra Pilot]

J-Spec TT MKIV...

Are the VVTi/Facelift de-catt pipes different to pre VVTi/Facelift ones?

 

If yes, then whats the difference...

 

Thanks

the first decat pipe is different, the exhaust bolt pattern on the flange is different.

Thanks, so this confirms the Turbo pack is different then!

 

This is what I am not certain about as I have previously read(here) that the Turbo set between pre & post VVTi models carry the same part numbers.(which does not add up)

 

Then also just picked from more searching that the Turbos or the pack assy is indeed different... Which will confirm the fact the Mounting flanges are different........

 

So another question, are the Turbos/Turbo pack a different set up and whats the differences?

Besides the flanges, and if just flanges, why, are they a better design now?????

 

Anymore input appreciated.

 

Thanks

Is the difference re the decat pipe just a change in the last part of the "elephants leg"? The bit of cast iron that comes off the EGCV component and connects to the 1st cat pipe?
