Sierra 6.2L Exhaust questions

2007 Sierra Denali AWD 6.2L

Engine light is on. Scan tool is showing cat code. Truck has 3" from the Y pipe to a side dump in front of the right rear tire through a Borla 3" race muffler. Y pipe and manifolds are stock. I just changed the rear O2 sensors at 100000 miles, so my thought process is i was wondering if the factory cats were not receiving enough back pressure with the side exit to allow the cats to work properly? And if the case would a header hi flow cat/y pipe set up work better and clear this code. Def don't wanna go back to a boring factory set up Laugh


Any help or suggestions would be appreciated

The only thing I can tell you is all the power comes up from the starter motor.xe tai van dongben 2 cho. Theres fusiable links and a thousand connections. I don't have schematics for the newer trucks. I can tell you this. When you get that 6.0 running correctly it's a strong engine. I'm sure you've done all the basic stuff. Then there are all those power connections and power distribution connections.Good luck I'll pass this on!

For the throttle body; use the adapter from torque rush (Dr-X) that module will solve throttle body swap issues. The 58x to 24x swap needs an adapter box from Lingenfelter. Get these two items, and you should start right up
