When taking off stock downpipe what should be replaced ?
 

Im taking off my stock exhaust off my T2 and putting a 3" tanabe DP , is there any gaskets or anything that i should buy ? or what should i replace while im under there taking off the DP

you can re-use both gaskets, but the gasket from the downpipe to the midpipe might break when removing. The downpipe to turbo gasket is reuseable.

Anything I can do to prevent breaking the bolts ? im going to load it with WD40 and let it soak for like a hour. and gently tug on them
