exhaust spring bolt torque?

doogle · 09-20-2010, 11:57 AM

I recently installed an axleback and I'm having a slight rattle at very low rpm (550ish). I determined that it is coming from the exhaust hanger on the car side of the rubber. I currently have the axleback torqued to 40ft/lbs, does anyone have the correct value or can check with a torque wrench on their stock car?

I retorqued the exhaust hanger on the car side (8mm socket) and the rattle went away, I probably loosened it when I was trying to yank out the stock exhaust from the rubber hanger. I checked the torque on the maddad to the midpipes and it is still at 40ft/lbs so I am going to leave it as there are no more rattles.
