Exhaust Size for HDi
|
Diesels need more airflow than petrols because of the higher afr, plus the heads on these suffer badly with back pressure. You could probably squeeze 250 and be ok, wouldn't want to push it more than that though.
That said, i've yet to see anyone find the exhaust to be a restricting factor at 2.5" simply because no-one tunes them that far lol. |
