Rear tailpipe 1968 Catalina vs. Grand Prix
 

Are these the same? I see a new one listed on ebay with the correct downturn, etc. but it's only listed for the Catalina. Is there any diff. between the Catalina and GP rear exhaust pipes on the 68? I know the Bonneville is longer, but wasn't the GP based on the shorter B-body?

They should be the same

Ok, thx. The reason I was asking was that the ebay ad said it does not fit a 68 GP, only the Cat. But I'm 90+% sure they were the same

If the pipe was for a single exhaust car, it may be rather different than 1 dual exhaust pipe. Good luck.

There may be a difference in pipe diameter. The shape may be the same.

The same.. I run into this all the time with my el Camino, I put Chevelle in the search engine and it all comes up!
