Yesterday, took off to WPE exhaust shop in San Angelo to get the O2 sensor bung welded in... and left the one with the E-Street kit on my phone charging stand (where I put my keys and whatnot at the end of the). Fortunately, an O2 sensor bung is an O2 sensor bung is an O2 sensor bung... the shop had some to spare, so all is good. Only charged me $50 to install the bung, weld up 6 U-clamp'd joints, and add some permanent hangers out back.
It was really humid yesterday (today as well - "swampy" as my pal from Phoenix mentioned), so I'll probably hold off on installing the E-Street until the weekend or sometime soon after the temps drop a bit more. Dave's taking off tomorrow morning to head back, so we're just gonna chill and enjoy the rest of the day BSing and whatnot.
