Zorst is just short for exhaust,
@ rochjas if you don't drive your Patrol hard you may not go into lime mode.
My exhaust is 3" all the way no noise what's so ever, combined with chip
gives pretty spritely performance. I have heaps of boost which doesn't bring on
limp mode. Fuel economy is 12.5/100 around town on 305 MTZs muddies,
X2 with Mudski shop around for the bigger items like bigger exhaust and tigged
intercoolers, I've found Diesel Smart to have best value for money C/O intercooler.
I have nothing to do with them, I just added up what they offered and compared to others.
The others only pressure tested to 30psi not 60psi like DS, 33% bigger like most others,
5 yr warranty beat that, and priced so its very affordable check their vendor page
