So i was trying to change my oil pan in my 1994 accord LX and the haynes manual.. (retarded) told me nothing of dropping the exhaust pipe just under the pan. I thought i would have clearnance but i was wrong. So now.. i broke 1 bolt on the cat to downpipe connection and im forced to break the other. The question is.. does anyone know what the gasket is i need for the downpipe to header? and the dowpipe to cat peices. also is grade 5 steel bolts strong enough and a grade 8 nut for each bolt going to hold in the place of original bolts i broke?

 

PB Blaster is your friend when working on exhaust. Match the grades on your nuts and bolts, 5 or 8 will work fine. As long as you don't over-torque them you have nothing to worry about. Use the factory torque specs and a torque wrench and you're golden.
