Guys i just put my 3"down pipe back on today and the boost has dropped just below 15psi, it was hitting 15psi and holding for a while with original cat on there, why is this?
Kindest regards

I would say less pressure build up in the system due to bigger bore pipework. Does it feel just as good?

Yeah feels just as good little more power as expected, cheers for that dude.
