CTS-V No Muffler with Kooks longtubes, hiflow cats, stock resonator only LS6
Another Exhaust experiment brought to you by Alan. This is a stock LS6 with Kooks LTs, hiflo cats, into the stock resonator, and straight piped, no muffler. There's a bit of old-truck clatter at WOT, but no real annoying resonance, and by far the meanest sounding combo to date INSIDE the cabin.
