Headers vs boost drop

[CWD]

How much boost drop would mid-length Bassani headers/catted Bassani X/Borla cat backs cause?

Well I have bbk lt's, o/r xpipe, and slp loudmouth catback and I probably lose about 1-1.5 pounds of boost.

This has been a debate on this forum for some time. Some people have put them on and lost around 1-2psi. I put them on and lost zero. I think it has to do with the rest of your setup.

It's good to lose boost in this case. Engine is moving air better. It allows you to spin the blower faster for same boost pressure and/or increase timing a bit, to get more power.
