just installed AS&M's & more
#13
I just got done installing my AS&M headers, accel wires, ngk tr55's, & egr delete! I am not getting my true duals until saturday so looks like i will drive it on open headers a few days.
i think it will run better with exhaust and some backpressure. 
my exhaust will be as&m's into true duals, with dynomax 23" bullet mufflers and the exhaust coming out one on each side behind the rear wheels.
surprisingly the 5.3 with open headers doesn't even seem as loud as my T/A with the 422 running through kooks headers into an x pipe bullets and dumps

Your T/A also had a far larger cam, ported & polished heads, and a larger motor...all those attrribute to more sound.
