FULL Custom Exhaust

[amschind]

So I've been rattling on about exhaust for a long time. The goal has always been a full custom system from heads to tailpipe. Today I made a big jump, with 49 state Flowmaster cats AND the crossover pipe dropped into the increased vertical clearance space made by my skid plates. I was concerned about O2 sensor codes, so I kept the stock cats and did a lap on 610, which got me the result below (eco mode, 87 gas, AC on, truck weighs like 6700# with all my crap, KO2s, huge grillgaurd/bumper). I won't Dyno it until I get the exhaust manifold replaced with the Full race manifold which they say will arrive in October or November and add a mild Livernois tune. Thus far, no cat codes (though the exhaust heat exchanger codes stay on because the exhaust heat exchanger is leaned against my fence).

I'm calling this a success.
