I don't know what the specifications are for the torque (in ft. lbs. please!) of the nuts for the studs on the stock manifolds to the stock y-pipe. I don't know what the torque is for the stock catalytic converter bolts that bolt to the exhaust hanger at the catalytic converter and to the catback exhaust system.

Thanks.

 

I've never torqued those to a specific ft/lbs....I just tighten them up nicely so they don't leak.

 

Y-pipe nuts are 20 lb ft, tightened evenly.

Cat hangar bolts are 30 lb ft.
