ZZ4, Chevelle headers, Xpipe, dual Magnaflow mufflers

It was nice and sunny today. I drove around all day. Put on about 100 miles. Ouch! All city driving!


ZZ4 at idle. Exhaust system - 3/4 length Chevelle headers, no cats, X pipe, dual Magnaflow 14" mufflers, and rear axel dump. Exhaust idle at 500 RPMs. Revs paused at 1000 RPMs and 2000 RPMs. Idle to near WOT bursts. Extra noise = loud LS1 fans and metal valve covers. Roller cam motors are loud at idle. Valve covers carry the noise.

You are overdue to put up a burnout vid.
