[Alberg30] attaching exhaust hose

[George Dinwiddie]

My exhaust pipe is 1-1/4" standard iron pipe, culminating in a piece of 
1-1/4" bronze nipple with a bronze water injection pipe brazed into the 
side at an angle.  According to 
http://ourworld.compuserve.com/homepages/mjvanvoorhis/t103.htm 1-1/4" 
pipe has an O.D. of 1.660", which corresponds pretty well to my own 
measurements (a shade over 1-19/32").

I'm trying to put a piece of 1-1/2" I.D. hose over this.  It looks as if 
the last time I did so, I cut the inner lining on the end of the pipe 
and allowed hot water and exhaust to get between the layers of the hose. 
  This has caused premature deterioration of the hose.

The problem is that this is a long way to stretch a hose.  The inlet to 
the muffler is only about 1-17/32" O.D. and the fit is not difficult. 
I'm worried about using any sort of lubricant, here, for fear that it 
will never seal well.  I've wondered if using a slightly cheaper exhaust 
hose (this is Shields premium hose, with the blue & green stripe down 
the side and spiral wire reinforcement) might stretch a little easier 
and last longer than mistreated expensive hose.

So, I thought I'd ask the collective wisdom.
