Was planning to leave the Hooker comments alone, but was crossing the border back into Canada the other day, the agent asked me if I had anything in the car, and I thought "just a couple of Hookers." Bad.
Almost 2 week update, about 500kms now. Went for a great drive today from Vancouver to Squamish and back up the Sea to Sky highway, listening to the exhaust the whole way with a big grin on my face. It still has the resonance at 2000 RPM when cold, but it seems to be reducing, and once warmed up it's effectively gone. On the highway at cruise it's very civil, with a nice low tone in the background that is no louder than the road noise, just distinct. When reving up more aggressively, it has a nice growl with minimal bark. Idle has really toned down and I don't feel like it will bother my neighbours, and the echo in my car port isn't too bad.
Wayne, I tried some different RPM ranges at speed, around 1500, 2000, and 2500 RPM, cruising steady then rolling into the throttle to approximate torque converter load up on an automatic. At 60-80 KM cruise is decent, light roll on is good, heavier roll on gives a deeper sound that I don't find to be drone but others might. 90-110 cruise on the highway, road noise is higher and rolling into the throttle seems quieter than the lower speeds as the road noise masks it more. Today on the Vancouver to Squamish run which it twisty mountain highway, same results as above with the tone getting a bit deeper going up hill, then almost silent going downhill, just some quiet gurgles. Note that it does gurge and pop at lower RPM on the downrev, though I wouldn't call it pop, just gurgle. When going down hill at 90-100 KMs I could hear the gurgles but they were soft. At city speed on the decel from 60 to about 35 KMs it makes a decel sound then gurgles below that. Are you still running stock mid pipe with your headers? The mid pipe is supposed to be what causes the gurgles.
