So anyway, I yanked the y pipe off and used a 3/8" bit to drill through the honeycomb on the back (no sweat, well maybe just a little sweat). Then used a screwdriver to break out the rest of the material. The tricky part was the front. First tried a flexible shaft with the bit on the end. The bit got caught up in the steel wool and snapped the shaft. No problem, I'll just yank it back out....right?....wrong! The shaft cam out with a firm tug, but.....the bit is still lost in the dark recesses of the cat. Time to switch gears I used a 3/8" bit to drill into the bottom of the pipe and then procedded to break out the rest of the honeycomb. Eventually the bit flies out along with some sizable chunks of honeycomb. Shop vac every once in a while to keep it clean and
voila
I tapped the hole and threaded a bolt into it for the time being until I can get it welded. Seems to hold good for now.
BONUS MOD
while I had the Y-pipe off I noticed a good 1/8" or better of a ridge in side where the two pipes y to one. I broke out the trusty die grinder and an hour later the inside of my y pipe was smoooooooth! I also sharpeded up the edge where the pipes come into one to smooth the air. Looks sweet and man you should have seen the amount of metal shavings on the ground. Probably shaved a pound of my weight!
Curiously I do not have a CEL yet. I am making MILs tommorow anyway. As far as a performance increase...I don't think it is near the 15% or so that some have thrown around. I do think the car pulls smoother through the rpm band and I hit the rev limiter twice while testing (something I never do) which tells me it is revving faster. I'm going to G-Tech as soon as it drys out around here.
