exhaust sizes for different turbos
Think I'm going to get my td05 16 swapped for an 18 from andy.
So, I currently have a full ppp exhaust fitted which is 2.5" iirc.
I believe the 2.5 up pipe gives better spool up for smaller turbos but will a 3" be needed for an 18g?
Or maybe a 2.5 up pipe with a 3" for the rest of the system?
What do you think will give the quickest spool?
Cheers
Chris
