My thrushes are pretty quiet until you hit it, then its got the fairly typical SBC crackle. Thats through long tubes and no cats as well FYI.
None of its in super great shape, but if you're in northern IL you should come pick it all up from me lol. Its all gotta go when the 5.3 goes in.
That muffler sounds like the aero turbines that the dodge trucks use... not a bad sound, the aero chamber design has proving hp increases in regards to air flow. Did i hear you are getting rid of your LT's? What brand are they?
