i am getting a set of LT's with the ORY
so what hooker should use 3" or 2.5"

 

dang, i was hoping for pictures of hookers

 

lol sorry not them hookers

 

if your gonna run a y pipe and a single exhuast pipe then the 3 inch . but if your gonna run true duals or a x pipe then two 2.5 inch hookers .

 

yep

 

so the single 3" muffler with 3" pipe in and out and the Y wont kill the low end
the truck is a 2000 rcsb with a 5.3
it has E-fans, WFM tune
sone 2 be getting the transgo hd with the servo, CAI and pulley

 

you will have plenty of lowend with the y pipe

 

when u say y pipe u r talking about the ORY?

 

yes the ory

 

with my setup i have tons of low end but it's hurting my top end. just by removing the catback at the y pipe i gain 3/10's in the 1/4. i'm going to probably do true dual 2.5" with x pipe, two hooker aerochambers dumped after the axle.
