Problem: The 63 buick special/skylark y-pipe may get bent right under the crossing under the transmission pan if the vehicle bottoms out. The crossing pipe in bent state is too close to the pan transferring heat into the transmission. Also, the typical exhaust tubing is bent with warped shape.
Solution: Replace the bent left exhaust part of the Y-pipe with mandrel bent pieces.
Parts: 1.75" OD x 16 Ga. x 4" CLR 90 degree bend. Left exhaust y-pipe bend. PTB Fontana,CA.
1.75" OD x 16 Ga. x 2" CLR 90 degree bend. Right exhaust y-pipe bend. PTB Fontana,CA.
1.75" OD x 16 Ga. x 6" CLR 45 degee bend. Center bend under the transmission pan. PTB Fontana,CA.
These three pieces make up the needed for the left side. The right is not included because it appears that not much damage is made at this side. CLR is the center line radius.
