will shavings hurt catalytic?
Friend offered me dyno time with wideband O2 (same guy that is giving me slicks). Looking at drilling a 7/8" hole about 2" above the upstream O2 on each tube (i have no inner fenders, nice and easy to get to), then have a bung welded to sheet metal that I can hose-clamp on for testing, then slide down to cover the hole once we're done.
Metal shavings will inevitably fall down towards the pre-cats. Would they hurt anything? I may try to stick a borescope magnet down and fish some out, doubt i'd get all of it.

are you running a stock y-pipe with a pre cat on each side?? i ended up taking mine and sawing in half in the center of the cats,tore the guts out and welded it back together,then used a spark plug non fouler to mount the downstreem 02 sensor,no codes after doing this..and should free up a few extra ponies as well,but,if your town is big on emissions checks,i wouldnt do it..

vacuum cleaner will do the trick and if you have a good drill it shouldnt let the filings fall inward anyway. but i dropped a 12 mm bolt in the turbo inlet on my gti and i used my shopvacuum and it pulled it right out. so it should do jusdt fine for little filings. but i was going to ask why not just use the stock o2 wide band or no the ecm should give you a reading anyway

I was going to start with an 1/8" bit then take over with a unibit.
