Anyone know the size of the tubing for a stock exhaust on a 91 accord lx? Need to buy a replacement piece to slide over the existing pipe.

 

Probably easier just to go out and measure it? It wouldn't be any more than 2"-2.25" O.D.

 

if I was able to measure it I would have. I can't get a proper measurement. Thank for the help.

 

Sorry if you don't have the exhaust there I guess that would be hard to measure. However if you do have the pipe there all you need is a piece of string and a ruler.

Wrap the string around the exhaust pipe. Mark the string where it overlaps. Take the string and lay it out flat on the ruler. That will give you the circumference of the pipe. In order to get the outside diameter you then take the measurement you got (circumference) and divide it by 3.4146 (3.14159 or Pi).
