LS Swap Help: Exhaust
We typically run a single 3" exhaust down the drivers side for installation simplicity and for exhaust tone. This is typically good for 350 hp.
On assembly, torque Y-pipe to header bolts to 18 lb/ft. After running the truck and reaching operating temperature re-torque bolts to 18 lb/ft again.
