Thread: U12 3inch downpipe gasket

Ok guys I demolished my old gasket I was wondering if you new any tricks to making a new one or buying one I tried the beer can well I used a pop can, but that didn't work any ideas? I know autozone use to sell gasket maker sheets they no longer do by me.

Holy crap i was able to edit this post!!!!!! also i have a T25Jpipe

The stock O2 housing is a really odd size. It measures 2.75" so a 2.5" flange is too small and a 3" flange is too large.

The 3" Hass downpipe I used had a full 3" flange, but Hass bored out the holes so it would fit on a facotry O2 housing. I used a 3" aluminum gasket and bored out the holes to match.
