i'm installing my catback, and on my cat converter there are springs before the bolt, and i cant compress the springs enough to put it through the whole and put the nut on the other side, what did you guys do to solve this problem? thanks

 

use muscle.
only thing to it. put the ratchet on the head of the bolt, line it up with the hole on the flange n push with all your might and turn the ratchet. once u get 1-2 threads on your set.
or have someone stronger do it

 

did you take off the donut gasket ? because the spring bolts should go on pretty easy . . .
